Great Contemparary Jazz as well
Agree with the Miles, Monk, and trane...but some great CD's have come out in the last 25 years as well.
Check Wynton Maraslis, "Black Codes from the Underground", Keith Jarrett Trio "Still Live". Pat Methany "Question and Answer", Steps Ahead "Steps Ahead", Kenny Garrett "Talking Book", Ralph Peterson Jr., "V", Dave Holland Quintet "Prime Directive".
You may like electric jazz as well(fusion). Check out Mike Stern "Time in Place", Miles Davis "We want Miles", Bob Berg "Cycles", John Scofield "Loud Jazz", John Pattituchi "John Pattituchi", Metro "Tree People". There is also plenty of fusion from the 70's (Return to Forever, Marivishnu, et al) but the recording quality of electric jazz back then was pretty lame. The first halfway decent sounding electric jazz CD I recall was Herbie Hancock's
"Headhunters".
