Mahler, pure and simple. I'm an old rocker (music major) who also played percussion/timpani in symphony orchestras. Others to listen to would be Stravinsky, as mentioned above, Shastakovich, Prokofiev, Bartok, Bruckner, Wagner (orchestral excerpts at least if you don't get into the opera).
I guess it kinda depends on what kind of rock you liked also, as to whether Bach, Mozart, etc. would do much for you. I listen to these some, but beyond appreciation for their work given the period, sonically they don't do much for me personally. I tend to gravitate towards more modern (verging on atonal) harmonic structures.
