I'm a huge hard bop fan... i've been collecting hard bop albums for like 7 years. Some of my favorites:

Art Blakey and the Jazz Messengers - A Night in Tunisia (this is probably my all-time favorite album/track)
John Coltrane - Giant Steps
Clifford Brown and Max Roach - Basin Street
Miles - Milestones
Dave Brubeck Quartet - Time Out

Some good non-hard bop albums (I'm a guitar guy, so these are the modern guitar wizzards that I dig just because they're really good)
Larry Corryel - Monk, Trane, Miles and Me
Mark Elf - New York Cats

:edit:I've met both these guys(^^^), and have signed copies of their cd's
