Since you like Miles I am going to assume you already have Bitches Brew, Kind of Blue, Sketches of Spain, etc.
Coltrane - Giant Steps, Blue Train, A Love Supreme
Brubeck - Time Out, Impressions of Japan, Jazz Goes to College
Thelonious Monk - Brilliant Corners, Straight No Chaser, Thelonious in Action, the recent release of Monk with Coltrane at Carnegie Hall is really good
Chick Corea - Sundance, Hymn of the Seventh Galaxy, Akoustic Band
Charlie Parker - Bird and Diz, Jazz at the Philharmonic. most albums are OOP but the Yardbird Suite compilation is fantastic.
Some more guitar/keys-driven fusion-y stuff: Pat Metheny Group - Offramp, American Garage, First Circle
Jeff Beck: Blow by Blow, Wired
Mahavishnu Orchestra, Inner Mounting Flame
