I assume the OP is asking for actual recordings, not just composers, so:
Anything by Murray Perahia especially the Mozart and Beethoven Piano Concertos...I like Mozart 19/23 - perhaps because it was the first CD I purchased back in 1985 for my swanky new $700 NEC CD player! Joys of shopping at J&R Music World...
Carlos Kleiber Beethoven Symphonies 5&7
Bach Cello Suites by Rostropovich...though there are a good dozen or more recordings all with their own merits.
That should give you a few places to start.
