I play the violin and piano and I listen primarily to classical music and have been collecting classical cd's for a long time. However, my one favorite recording of all time, is Stravinsky's Rite of Spring conducted by Leonard Bernstein, the 1958 recording. Not the greatest SQ (if you're just looking for recordings to show off the capabilities of your headphones, then while this is a decent quality recording, look elsewhere), but by far the most powerful performance of Stravinsky I have ever heard. I have listened to a great number of Stravinsky recordings, and no other recording even comes near the power of this one. This is the closest thing to Stravinsky's own vision of the piece, as evidenced by his own review when he heard it: "This was an explosive performance of the sort that is alleged to have brought the following sardonic review from Stravinsky the first time he heard it: 'Wow!'"
Its gotta be the 1958 recording though; the later recording made by Bernstein had a far less talented orchestra (the brass section especially is far inferior). Too bad the only version of this that is still somewhat available is the Sony Royal Edition series no. 87 of 100, which you can find used on amazon occasionally. I picked up my copy from a local public library sale several years ago for a few bucks, the used versions on amazon now are going for over $100.
Edit: Sorry, just read your sound quality requirement, so this is probably not quite on the level you are looking for. But for musical performance, you won't find any better. Also to everyone else in general: for classical recordings, I tend to dislike the really sterile, squeaky clean sound of digital recordings; how about you? Although digital recordings mean no background hiss, I somehow find that I much prefer listening to older analog recordings even if they have some background hiss; I feel like the older recordings just have more depth to them, and a lot of instruments (string instruments especially) tend to sound more real. Idk, I don't listen to vinyl, but maybe I'm hearing a similar sort of difference?
