Damn, some of you guys have had some pretty cool experiences.
Here are a handful of bands that just blew me way...mostly because of just the amount of evergy they each put forth.
Tom Petty
Widespread Panic
Nine Inch Nails
The Dead
Marilyn Manson
Mecca Bodega
Also, for anyone that just loves to go to shows...I highly recommend attending Bonnaroo next summer. 2003 was it's second year, and it was just unbelievable.
