Really enjoying Koyunbaba, Op.19 as played by Alexander-Sergei Ramirez, especially movements 3 and 4. Also, some of Mozart's last five symphonies, like 36, 38, 40, and 41, are really growing on me now. Bach's Art of the Fugue (all parts), especially the Musica Antiqua Koln version, is incredible.
I think I'll morph this thread into a rambling classical music rec list, since I'm quite into it now. Because of my playing, I lean very, very heavily to classical guitar or composers friendly to transcription. But I will also try to post new symphonic classical releases that catch my ear too. I really like antique instrument and fingering groups, as it's nice to hear the music in the flesh, the way the artist imagined it.
