How many bands would you consider yourself a hardcore fan of?

Bob Dylan *
Neil Young
Rolling Stones *
Led Zeppelin *
Miles Davis **
John Coltrane **
Quicksilver Messenger Service *
Prince
George Clinton and projects ***
Fred Anderson
Ornette Coleman **
Anthony Braxton ****
Art Ensemble of Chicago *****
Sun City Girls ******

* I own at least 6 bootlegs each by all these artists.
** yes, I really do have just about everything, thanks to the glory of boxsets. Got both artist's Prestige sets, Miles's complete Columbia and Capitol sets, John's Atlantic and Impulse sets, Miles's Ascenseur Pour L'Echafaud and various 80s sessions, John's Bethlehem recordings and various Blue Note appearances as leader and sideman... Even a few Coltrane boots. Oh, and I'm pretty sure I own close to every note Ornette Coleman has played.
*** got just about everything. All the Parlet albums, all the Horny Horns albums, the Eddie Hazel lp, the Godmomma lp, the George Clinton "Family Recordings" series of CDs ... sheesh, even the "By the Way of the Drum" 12" and the freakin' Jimmy G and the Tackheads lp.
**** I've got everything up until about the mid-80's
***** Ditto (basically, everything up until their stint on DIW)
****** Yeah, I am a collector scum. I really do have just about every note these guys have officially released.

Talk Talk
Orbital
Outkast
Disco Inferno
The Stone Roses
Bark Psychosis

But that's totally subject to change every five minutes, and doesn't take into account all the artists who I love one and a half albums or a few singles or just one damn song by. I really wouldn't want to never be able to hear "Groove Is In The Heart" or 3ft High & Rising or "Lazarus" or Dig Your Own Hole or "I Want You Back" or In A Silent Way again, but there are big chunks of each of those artists' output that I'm not arsed about in the slightest.

Back in the day - the Manic Street Preachers

Also the Boo Radleys, Teenage Fanclub, the Trash Can Sinatras, Jesus and Mary Chain to some fair extent as well.

I've been fine without Nirvana. Really. But I've got to listen to Killing Joke on vinyl at least once a day. And I'm a huge Foo Fighter fan and have to have those cds.

I'm more of a 'hardcore' Dave Grohl fan than anything else, really.

MBV
Drugstore

joy division
my bloody valentine
captain beefheart
spacemen 3
slowdive
jesus and mary chain
royal trux

and startin to get hard over:

the make up/scene creamers/weird war

and hope to one day be the hardest at:

interpol
dead meadow
acid mothers temple

well, soon as they have enough stuff out there to be hardcaw over.

i guess. i just don't have it all at this stage... add them to the attempting-to list.

elliott smith
wilco
tom waits
opeth
radiohead

got all the above's records and have played them all to death, have seen them live numerous times (except waits :( ), have dug out most of the rarer stuff, etc.

i'd like to include other bands like the cure, my bloody valentine, katatonia, fugazi, but i'm not quite there.

working my way up to:
Beach Boys
Love
Eno

And that's about it, I think.

and 1000 others

There are considerably more Genesis tracks that I dislike (OK, I could have said Genesis 1970-1980 to make it more accurate)

MX-80 (Sound)
Led Zeppelin
Beatles
Love
John Coltrane Quartet (and, eventually, Quintet)
Velvet Underground
P-Funk
Captain Beefheart
minutemen

Black Sabbath, Pere Ubu, Van Halen, Motorhead all coulda made this list but for unfortunate changes in personnel that altered 'em forever. (My support for most bands is mile-wide/inch-thick.)

high school:

The Misfits/Samhain
Throbbing Gristle
Velvet Underground
Swans
Sonic Youth
Einsturzende Neubauten

college:

Nurse With Wound
Enoch Light
Borbetomagus

AMM

grad school:

Iannis Xenakis

In terms of sheer number of releases owned it is a tie between Nurse WIth Wound and Enoch Light.
