Barber: Adagio for Strings (Bernstein) [not too original, I know]
Brahms: Six Pieces for Piano, Op. 118 (Perahia should record the set soon, and he plays them absolutely superbly, as I’ve heard him do only two weeks ago in concert)
Brahms: Piano Concerto No. 1 (Rubinstein/Reiner)
Richard Strauss: Also Sprach Zarathustra (Reiner, though the sound is a bit dated)
Bach: Goldberg Variations (either Gould’s 1981 account or Tureck’s 1958 version)
Horowitz: The Historic Return (his 1965 Carnegie Hall recital, with sound that many believe best captures the pianist’s floating, soulful tone)
Bach: Suites for Unaccompanied Cello (many good versions, but perhaps Tortelier or, if dated sound is okay, Casals)
Beethoven: Symphony No. 5 (Carlos Kleiber)
Shostakovich: Symphony No. 7, ‘Leningrad’ (Maxim Shostakovich, the composer’s son)
