The late-'60s/early-'70s blues-rock outfit Mother Earth was led by singer Tracy Nelson and issued several somewhat underappreciated releases during their time span. Nelson was originally from Madison, WI, and it was while attending the University of Wisconsin that the singer was discovered by producer Sam Charters and was eventually signed to a recording contract with the Prestige label. 1965 saw the release of Nelson's solo debut, the folk-based Deep Are the Roots, and when it didn't exactly burn up the charts, Nelson decided to relocate to San Francisco, with the hopes of forming a more conventional rock outfit. Shortly after arriving on the West Coast, Mother Earth was formed, which led to performances at the famed Fillmore West, opening for the likes of Janis Joplin, Jimi Hendrix, and Eric Burdon. After an appearance on the soundtrack to the 1968 motion picture Revolution (which also featured the Quicksilver Messenger Service and the Steve Miller Band), Mother Earth signed with Mercury Records and issued a steady stream of releases until the early '70s.
