With 50 Foot Wave, Kristin Hersh unleashes a deluge of formidable rock only hinted at in her work with Throwing Muses and on her own. In the late '90s and early 2000s, her music with those projects was largely introspective and acoustic-based, so 50 Foot Wave's amped-up sound and direct lyrics -- introduced on 2004's self-titled EP -- were a distinct change of pace. Though 2005's debut album Golden Ocean proved the power trio had more than enough ideas to fill a full-length set of songs, they preferred short-form releases, and with 2006's Free Music EP, a pay-what-you-want release, their innovation extended beyond the studio and stage.
