Is there anybody other than Bach who ever wrote a significant number of fugues? They are like musical math and JS seems to have been the ultimate savant of that form. Other composers seem to have labored through a few of them, but Bach could spew them out like a garden hose.
Well, what do you call significant? It's not just fugues; well you could say Bach was the ultimate savant of ANY form he cared to write in, AND with whatever form, or
thing, you might want to talk about, he was just insanely prolific, whether that was writing a full cantata per week for however many years he was at Leipzig (and elsewhere) and that's not including holidays (we have a couple hundred of those surviving, and the guess is that we have lost about 2/3 of his output on those) . . . to having
twenty children was it?!? I want to know how much of the lost cantatas became sandwich paper.
So, given that most any other composer that the general public may be familiar with by name was simply never as prolific . . . most any set of fugues since then is typically some sort of tribute to Bach just by nature. Heck, forget a set of fugues, even just one fugue is almost inherently a tribute to Bach. The first large set of fugues I think of is by Shostakovich for keyboard, an obvious reference/tribute to the WTC, preludes/fugues in every key. Of the bits I've heard (I don't own this stuff), I do not recommend the Jarrett version (I am a big fan of some of his jazz though), and I do recommend Ashkenazy. I have never heard Landowska playing them. I have no idea who this guy is below, but the video is nice, and I think the fugue starts a few minutes in.
I own the complete string quartet cycle by Shostakovich as performed by the Borodin quartet, and the quintet is played with Richter there. Well, I am not familiar with the ensemble performing below, and the video is not even the entire fugal mvmt in its entirety, but anyways I enjoy not only this mvmt but the entire quintet. The recording I have, I would easily use it as a demo disc (and the quintet is a live performance). The Scherzo mvmt, I think it's called (well it should be if it isn't) kicks seriously major butt.
Here is an example of yet another reference/tribute, but this time to Bach's Sonatas and Partitas for Solo Violin where I heartily recommend the Szyreng recording. I've owned multiple renditions over the years, including Perlman and Milstein, if not more. Well, the Bartok fugal mvmt here will scare most people here away I fear. His string quartet cycle is considered among the most important, along with Beethoven, Haydn, Shostakovich, etc. I have a Frenchman playing this work (can't remember his name), but my favorite rendition I've heard is actually on the Naxos label, but there is no way I'll remember the performer's name.
I'll end this post with an American composer, Barber. This subject is pretty jazzy in nature, but again I fear it may be a bit challenging for neophytes. This mvmt kicks azz. I picked Horowitz, so there is no video here. The other videos, I'm not sold on the recording . . . from the little I checked out quickly.
