Paper Diamond's stock just rose significantly. The Boulder-based act led by Alex B. (aka Alex Botwin) of Pnuma Trio and Elm and Oak, has been added to the Outside Lands festival happening a few weekends from now in San Francisco. Have you seen the lineup? He'll be in some pretty impressive company alongside Arcade Fire, Muse, Girl Talk, MGMT, Phish, DeadMau5, STS9, Black Keys, among others. Looks like the Pretty Lights (who played last year) affiliation isn't hurting a bit.
