Fuck!
I think the 2000s have been great musically speaking:
Anything by livefastdie is fucking great! Bandana Thrash is the full length, but the 7"ers are great, too...and there's a lot of them.
King Khan w/ the Shrines is good (as is King Khan BBQ Show)--What Is!?!? continues to blow my mind.
Deadly Snakes: Ode to Joy and Porcella are both classics
Digger and the Pussycats: Young, Tight, and Alright; Watch yer Back; Let's go to the Hospital--stripped down rock n roll
I'm sure there's more...the 2000s have been a solid decade for rocknroll!!!!
