what recording to choose for goldberg variations?

Today marks the 335th birthday of Johann Sebastian Bach, without a doubt one of the tallest standing giants on whose shoulders stands a significant portion of our musical canon. What better time than his birthday is there to take a look at his life and his works?
I will leave a short biography below, share some resources, and share some of my favorite pieces of his. I welcome everyone reading to join me below.
Biographical Outline
Bach had a fairly mobile life, and spent short periods in many places. For the sake of brevity, I will gloss over the shorter periods, and focus more on the more significant ones.
1685-1703

• Born in Eisnach, Saxe-Eisenach on March 31, 1685.*
• The Bach family was very musical: his father, many uncles, many cousins, and his siblings were all professional musicians in some sense.
• His mother died in 1694, and his father died shortly thereafter; Sebastian Bach moved in with his older brother, Johann Christoph Bach, who lived in Ohrdruf (1695).
• Enrolled in the St. Michael's School in Lüneburg in 1700. *The calendar at the time would have read March 21, 1750; this is due to difference in the Julian and the Gregorian calendar systems

1703-1723

• After graduating (1703), Bach obtained a position as a musician of Duke Johann Ernst II's court in Weimar; became the organist at the "New Church" (now the "Bach Church") in Arnstadt later that same year. (this post is the setting of two famous stories of Bach: the incident with the "nanny-goat bassoonist", as well as his two week leave to travel in which he walked 280 miles [450 kilometers] both ways on foot to visit Buxtehude [he was absent for 4 months during his "2 week" leave].)
• Spent 2 years in Mühlhausen as organist at the Basius Church (1706-1708); he met and married Maria Barbara Bach four months after his arrival
• Returned to Weimar to become the organist at the Ducal Court (1708-1717): became Director of Music (1714), which entailed a monthly composition of a cantata; spent a considerable amount of time transcribing Italian works during this period; wrote the English Suites during this period; wrote the preliminary works that would become the Well Tempered Clavier during this period.
• Dismissed from his Weimar post in 1717, and even jailed for a day over his stubbornness over the dismissal.
• Hired as Kapellmeister for Leopold, Prince of Anhalt-Köthen in Köthen (1717-1723): Leopold did not require much music for services, so much of Bach's time was spent on secular compositions during this period; Bach's attempted visit of Handel (a 22 mile [35km] walk away) happend during this time (1717)-Handel wasn't in town; his first wife died (1720); he met and married Anna Magdalena Wilcke in 1721; completed the Brandenburg Concertos by 1721; completed the first book of the Well Tempered Clavier in 1722.

1723-1750; The Leipzig Years

• Appointed Thomaskantor of the Thomasschule at the St. thomas Church in Leipzig (1723): wrote the majority of his known cantatas within his first 3 years here; completed the French suites within the first 3 years as well.
• Became director of the Collegium Musicum (1729-1737): many of his secular compositions during this period were intended for this organization, to be performed at the famous Café Zimmermann in Leipzig.
• Published his four Clavier-Übung during his time in Leipzig (discussed in the "Compositional Output" section).
• Composed the bulk of his Mass in B Minor in the mid-1740s
• Completed the second book of the Well Tempered Clavier in 1742
• His famous visit to Frederick II of Prussia in Potsdam occurred in 1747
• Began a large part of his "The Art of Fugue" in 1742, which he would prepare for publication and work on until his death.
• Bach, becoming blind, had eye surgery performed by the fraud John Taylor in early 1750; JS Bach would die several months later from infection on July 28, 1750.

Compositional Output
How can I even begin talking about Bach's compositional output...
This is a rare instance where I feel like simply dropping a link to a Wikipedia page is the best thing to do. This is a page about Bach-Werke-Verzeichnis [BWV] "Bach Works Catalogue". This catalogue is the standard way of organizing Bach's many works, and this page contains information on all 13 categories within the catalogue, and endless rabbit holes to fall into.
His four Clavier-Übung I mentioned earlier are as follows:

• I - The 6 Partitas (1726-1730; published 1731)
• II - The Italian Concerto and the French Overture (1735)
• III - The German Organ Mass (1739)
• IV - The Goldberg Variations (1741)

His output is stunning not only due to its volume and variety, but also because each piece that we have is so packed full of music. There are few works by JS Bach that we have that are simply trivial, throw-away pieces; they are all so well-composed, so full of craftsmanship, that nearly each piece invites one to devote themselves to the study of it.
Resources

• gerubach is a YouTube channel that, as far as I can tell, is incredibly run by a single person. The ultimate goal of the channel is to have a video with scrolling sheet music for every single composition by Bach. This channel is truly a great resource.
  
• Netherlands Bach Society is another channel with a similar goal. However, this group focuses on creating new, extremely high quality (both in audio/video and in performance) recordings of every Bach piece. Their performances are all historically informed. They have some of the absolute best performances of Bach's cantatas and Passions I have ever heard. Along with nearly every performance, they upload a sister-video that is an interview with some of the performers; these videos are always very informative and interesting.
  
• Voices of Music does not focus soley on Bach, but rather all of the baroque repertoire. They are another historically informed ensemble. They have a great deal of Bach recordings, and their videos are of very high quality.
  
• Ashish Xiangyi Kumar has only a small amount of content relating to Bach, but it is of such high quality that it deserves a mention. The videos feature scores, high-quality audio, informed analyses, and great discussion in the descriptions.
  
• For those few unaware, IMSLP is an incredible source for sheet music. The site has nearly anything you could want that is in the public domain.
  

Personal Favorites
It will take a lot of discipline to keep this section short. I will also skew away from the more well-known pieces; I personally adore much of the WTC, but so do most others, and they are already aware of the pieces. The same goes for many other works. (I do have future plans for a post solely dedicated to the WTC, that goes into more depth, incidentally).

• BWV 532 - This Prelude and Fugue for organ has some of the most incredible dissonances I've felt. I really urge you to listen to this with good studio headphones or loud speakers; feel the power of the instrument-the adagio section of the prelude will hit you like a ton of bricks.
  
• BWV 572 - Another great organ piece, this time a Fantasia. The Grave segment is great. If you don't want spoilers, stop reading: the final cadence of the Grave section is quite the surprise, a deceptive C#dim7 chord.
  
• BWV 578 - This organ fugue has a very catchy subject, and deserves its fame. This piece (and this video) is great for teaching; it's a great way to introduce beginner students to the concept of counterpoint, as they can "see" the voices, and the subject is so memorable and distinctive.
  
• BWV 1023 - This violin sonata is great. The Adagio is so beautiful.
  
• BWV 1016 - Another stunning violin sonata. The second Adagio is really something else. If you listen to the harpsichord parts, you'll realize this is actually a disguised trio sonata.
  
• BWV 1018 - This is a sonata for violin and keyboard. I hate to sound like a broken record, but the Adagio is 100% worth checking out. Bach really had great skill with getting these kinds of feelings out of a violin.
  
• BWV 1043 - This is the Largo movement from his D Minor double violin concerto. The way the violins speak to each other is incredible. It's very easy to be absorbed by this music. Here is a full performance; I simply like the previous performance of the second movement better.
  
• BWV 245 - Bach's St. John's Passion really must be experienced by everyone, and this is an incredible performance of it. Few things in music grab one as much as the opening, "Herr unser Herrscher", of this masterpiece.
  
• BWV 227 - This is one of my favorite motets by the composer. The first verse is very memorable, of course, but Bach also goes on to showcase some incredible 5-part polyphonic writing later on.
  
• BWV 8 - This cantata is one of my favorites. I don't know what it is, but something about this one really sticks with me. The description of this video has some good information.
  
• BWV 997 - This is an incredible suite played on, and composed for the lute-harpsichord. Unknown to many, this was one of Bach's favorite instruments (read the description of this video: the information is accurate). Bach loved the sound of the lute, but wasn't fond of its limitations in what it could play compared to keyboard instruments: the lute-harpsichord was the best of both worlds to him.
  
• BWV 831 Mvt.I, Mvt.II, Mvt.III, Mvt.IV, Mvt.V, Mvt.VI, Mvt.VII, Mvt.VIII, Mvt.IX, Mvt.X, Mvt. XI - This is his French Overture in B Minor. Glenn Gould's performance of this work is a strong contender for my favorite keyboard work of all time. The counterpoint is amazing; it's truly some of the most perfect polyphony I have ever heard. The voices really feel... "real". This is a true discussion between these disembodied voices. If you have any kind of an inclination towards counterpoint yourself, give this a listen with some focus: with headphones, or driving around a quiet neighborhood, or lying in bed with a speaker playing, or anything like that.
  

Bonus

• A couple years ago the very talented musician and content creator Nahre Sol made an interesting tribute to Bach: "Happy Birthday" in the style of J.S. Bach. I feel like it is apropos to link to it here~

Afterthoughts
There is nothing I can say about this composer here that hasn't already been said a thousand times, in a thousand ways, by a thousand musicians more talented than I. There is also no need to convince anyone reading this post of J.S. Bach's compositional prowess. My simple hope is that I can spark some more exploration into this great man, as well as hopefully spark some discussion in the comment section.
Happy Birthday, Sebastian, and happy listening for everyone else~

Background

I was 4th of 9 children and grew up in Texas and Louisiana in a devout LDS family (all 6 boys missions, all 9 children graduated from BYU, 9 temple marriages, etc.).
I served a dedicated mission in Scotland, graduated from BYU in microbiology and did grad school in Texas focusing on the bioinformatics of mass spectrometry based proteomics. Did a postdoc at CU Boulder and was an assistant professor at BYU for about 4.5 years (really enjoyed my time there) but left to become a programmer. [No, I wasn't fired or let go--I was easily on track for tenure/CFS, but felt like my funding level was insufficient for the science I was trying to do and for the way in which I felt I could best help the department.]
We have 6 children. My oldest is about to start up at USU. My youngest is starting 1st grade.

Interests

I love walking, running, and hiking barefoot. I've summitted several of the mountains and peaks around Utah County (like Nebo and Timp) barefoot. My wife and I do one or two 6 mile walks around Provo most every weekend.
I love good classical music (I don't love boring classical music!) especially orchestral works, choral works, the organ, and harpsichord. Bach is my favorite composer. My user name is based on one of the first pieces that my brothers and I were really excited about when really exploring Bach's organ work for the first time (BWV 549). We were excited by the realization that there was more out there than just Toccata and Fugue in D minor (BWV 565). I prefer Bach perfectly timed (so as not to preference any voices), so I sometimes make midi recordings like this.
My wife and I enjoy going to concerts together--in the past couple of years we've been to see Depeche Mode, OMD, Pixies/Weezer, the National Parks, Smashing Pumpkins, and just last weekend Erasure. Since my faith transition a few years back, I've been re-exploring "secular" music again (currently enjoying Allesandro Cortini's instrumental stuff, Lantern By Sea, Artesia, and the album EE4C by Easily Embarrassed).
My favorite novel is Pride and Prejudice, but I also really like Sanderson, like most of you. I'm reading Brandon Mull's Fablehaven series at night to my kids right now. I love researching and writing on various topics (especially LDS stuff), so I end up reading far more non-fiction than fiction.

Current

Since my faith transition I've been trying to figure out how to help make LDS faith transitions more "successful": to preserve mental health and relationships (marriage, family and friends) that maybe shouldn't be lost to a faith transition. Just the other week, after a lot of discussions and preparation for the past year or so, I helped kick off the first informal Mormon-FormerMormon-Dialogue with the BYU religion department (also with A-B-C-D-4-3-2-1, FlirtToConvert, and JonOgden).

• brief sketch of my faith transition
• summary of my beliefs now

note: there is way more than enough to dox me with this post; my only preference is that my username not readily co-appear with my real name in google searches, but I'm perfectly fine that people figure out who I am IRL.
edit: minor edit around concerts

I'm in the process of creating a MIDI interpretation of J.S. Bach's Aria with Divers Variations, otherwise known as the Goldberg Variations, and I would like to ask this subreddit how they think this work should be interpreted. Here are some questions for consideration:

• Which recording of the GV is the best for listening? (Harpsichord preferred, but piano is also acceptable.)
  
• Which recording is best for studying?
  
• Should all the repeats (ABAB), some of the repeats (AAB, ABB), or no repeats (AB) be observed?
  
• Tempo: how fast is too fast? How slow is too slow? Are there certain variations that, with too much or too little speed take away from the GV as a whole? 1
  
• This last question is for harpsichordists: How important is registration for the GV? Does it need to blow the listener's mind, or not take away from the work itself?
  

I probably left a few questions out, but those are the ones I wanted to discuss.
