@Inlander: They got lumped together because their genesis(s?) occured close to eachother, and they both utilize larger bands, multiple horn lines, and swing-time. I know they are not the same. Also, having favorite types of jazz is not a bad thing. I love Hard Bop more than anything, but that doesn't mean I don't love jazz (if not just the general statement of 'music') in (almost) all its forms. Jazz (and music) snobbery is caused solely by a person being an asshole, which I am not. Also, if you don't like fusion, check out these three songs:
Miles Davis - What I Say
Herbie Hancock - Watermellon Man (the cut off of Headhunters)
Weather Report - Birdland
@Chuck: I said post-1985.I guess I should've called the choice Nu-Jazz/Experimental Jazz, but whatever.
@Sam: Sun Ra is sometimes free jazz, sometimes ultra-spazzy hard-bop, always experimental, and totally fucking mad. SUN RA IST KREIG!
@Tago Mago: Where is the Ornette in your free jazz? THE INVENTOR! THE INVENTOR!
