Yes, that had to be years ago. Desmond died in the late 70s when he was in his early 50s, I believe. Far too young. By the way, Dave Brubeck also did some fine work with Gerry Mulligan.
But in my opinion, possibly the greatest jazz album of all time is Miles' "Kind of Blue" from 1959. It's hard to go wrong with a lineup that included Bill Evans (who Miles brought back for several tracks of this album), John Coltrane, Cannonball Adderley, Jimmy Cobb and Paul Chambers. All were stars.
Speaking of Coltrane (who also died too young), "My Favorite Things" and "A Love Supreme" were also fantastic albums. Both albums had McCoy Tyner on piano, another pretty good musician. He did some great solo work after leaving Coltrane's group.
