This intriguing early-'70s Southern Californian group featured the talents of singer/songwriter Merrell Fankhauser (who was also at the helm of cult classics in the '60s by Fapardokly and HMS Bounty) and Jeff Cotton, previously slide guitarist with Captain Beefheart. Their sole album (from 1971) is a gem of the late hippie era, combining the fractured blues-based tangents of Beefheart with the loose flow and stoned lyricism of bands like the late-'60s Grateful Dead. After a couple more singles, Mu moved to Maui and cut a fair amount of unreleased material before breaking up around 1974. Their eponymous album, as well as a lot of their unreleased material, was reissued in the '80s. ~ Richie Unterberger, Rovi
