Youtube and Amazon totally rock - just spent a couple hours deciding on a half dozen or so blues albums for the wife. In between I'm listening to her new find, Shovels and Rope, whose three albums now comprise my entire Christmas list.

Odd in that I'm coming from a background of medium to big, technically excellent bands like the Dead, the Stones, the Goo Goo Dolls, the Foo Fighters, Old Crow Medicine Show, etc. but this unaccompanied Americana husband and wife duo playing an assortment of battered guitars and a drum set literally scavenged from the dump is currently my favorite band.
