O.A.R. is playing at DeepRockDrive next week. If you're into the Dave Matthews Band you should check it out. There are definite similarities, in fact, they tour with DMB and will be playing together at the Gorge this September.
Also, check out this Sprout I made - what an amazing site for creating live web widgets. Amazingly simple and hugely powerful.
Thanks, Jeff, for making me build my first one. I'm hooked!
