Check out this original first printing Armadillo World Headquarters poster for a Tracy Nelson and Mother Earth concert which took place on 12/13-14/74.
The late-'60s/early-'70s blues-rock outfit Mother Earth was led by singer Tracy Nelson and issued several somewhat under-appreciated releases during their time span. Born in California but raised in Madison, WI, Nelson began playing music when she was a student at the University of Wisconsin. Nelson began singing folk and blues at coffeehouses and R&B and rock & roll at parties with a covers band called the Fabulous Imitators. In 1964, she recorded an album for Prestige, Deep Are the Roots, which was produced by Sam Charters. Two years after recording Deep Are the Roots, Nelson headed out to the West Coast, spending some time in Los Angeles before settling in San Francisco.
Upon moving to San Francisco, in the midst of the era’s psychedelic explosion, Tracy formed Mother Earth, a group that was named after the fatalistic Memphis Slim song of that title. The formation of Mother Earth led to performances at the famed Fillmore West, opening for the likes of Janis Joplin, Jimi Hendrix, and Eric Burdon.
After six Mother Earth albums for Mercury Records and Reprise Records, Nelson continued to record throughout the ’70s as a solo artist on various labels. In 1974, she garnered her first Grammy nomination for "After the Fire Is Gone," a track from her Atlantic Records album, a hit duet with Willie Nelson. Willie (who, despite the rumors, is not related to Tracy although he contends they just might be "the illegitimate children of Ozzie and Harriet") provided liner notes for the album CD, noting of Tracy’s remarkable instrument, "that tremendous voice has only gotten better over the years."
