"Crazy on You" is one of my favorite Guitar Hero 2 jams, and the Decemberists rock so hard on it, thanks in no small part to vocal powers Shara Worden and Becky Stark (but mainly Shara Worden). This was live in St. Louis, and pretty great for a fan vid. CHECK IT!
Side note: when I say Shara with My Brightest Diamond, I was less than impressed, but her work with the Decemberists has been stellar! Maybe it all happened when she cut her hair.
