NIN
I like alternative a little more than rock nowadays though.
The Strokes.
KMFDM
I wanna say Pink Floyd, but I am not really sure
is that the name of the band or an acronym?
Dead or Alive 
Saxon
-Imp
I couldn’t possibly choose just ‘one’!
When I was in secondary school it would have been Nirvana hands down, closely followed by the The Doors. Now however, I do not think I have a favorite band.
Bishop - I love your avatar! I love Harry Potter!
Its weird, these days I seem to listen exclusively to solo artists; Dylan, Springsteen, Young, Waits, Cave. But I used to listen only to groups. So I dunno, Husker Du, Pixies, Joy Division - those bands were pretty awesome.
You have a great taste in music.
It’s an acronym, but a German one: Keine Mehrheit Für Die Mitleid. It translates to “no empathy for the majority.”
Canned Heat.
As if you had to ask. Everybody knows Canned Heat rules.
Slipknot.
Man, slipknot grosses me out. I just read up on them. That guy pukes in his mask and then throws it on the crowd. YUCK.
( What a expressive political statement he is making. 
)
Iron Maiden … FTW, Up the Irons!!!
Steve Harris is your daddy!!!
tool
Who’d have guessed it would be Tool? 
(I couldn’t resist that one, Trahne
