Great site that features a lot of good bands preforming acoustic-ish stuff (in the Pink Couch section, that is). Halo Fauna, Defiance, Ohio, Andrew Jackson Jihad, Spoonboy, Bridge and Tunnel, Matty Pop Chart, BTMI!, Ghost Mice, Lemuria and many, many more! Check it out. I love it.
And there's also a few live performance by Best Friends Forever, Iron Chic, Good Luck, Heathers, Slingshot Dakota (covering "Waiting Room"!) and tons more.
Bookmark that, man.
