I was waiting for you to chime in on this thread.
I was listening to Nicole Atkins earlier today - I dig her. She's on the list.
The Redwalls got upgraded to bolded font...I really like them!
I saw MMJ at ACL last year. They did put on a great show - with a Hawaiian Tropic theme. The lead singer wore a blonde wig and grass skirt. I like them, but don't think I need to see them again during sxsw.
I've heard of Kate and Rocco, but am not familiar w/ their music. I'll check them out and the others you mentioned too.
BTW, I'm a HUGE Grace Potter fan now - thanks!
