Look no further. You've come to the right place.

I've got many suggestions, but I'll keep it relatively simple with a bunch I just grabbed from my stacks:

1. Bach (anything), but do get any good rendition of the Brandenburg Concertos. 2. Mozart (anything), but Symphonies No 40, No 41 are interesting.. 3. Beethoven (anything), but try Symph No 5 and No 7, Wiener Philharmoniker (that's Vienna Philharmonic) has a nice recording, Carlos Kleiber conducting (Deutsche Grammaphon) 4. Prokofiev Piano Concertos (No 2 in G minor and No 3 in C major)...do run and buy this one with Royal Concertgebouw Orchestra, with the amazing Horacio Gutierrez on Piano, Neeme Jarvi conductor 5. Stravinsky (the Rite of Spring), I like the Leonard Bernstein CD with New York Philharmonic, but there are other choices for this one out there.. 6. Shostakovitch symphony No 5 (my 2 fav versions and the only ones I own, but there are several others...with Leonard Bernstein the first recorded in 1959 NYPO, and the 2nd a little more edgy version recorded live in 1979 NYPO live in Japan...take your pick). If you love music, this symphony will move you greatly...it's very powerful, transcendent really.. A close 2nd is his Symphony no 8). But...I love all things Shostakovitch, he is probably my favorite classical composer. 7. Felix Mendelssohn Symphony No 5 the Reformation Symphony, London Symphony Orchestra, Claudio Abbado conductor. 8. Claude Debussy, Preludes for Piano, books I and II (some of the greatest piano music ever written, outside of Chopin IMHO) 9. Arvo Part (anything), but I really love Litany, in particular the piece Trisagion. He's on ECM...very easy to find.

Tip of a huge universe, but those things will get you started. Pick a couple and your ears will dictate where else you might want to wander.
