As her career began to fade in the late 1950s and early 1960s, she left Houston and relocated to the San Francisco Bay area, "playing clubs in San Francisco and L.A. and recording for a succession of labels", notably the Berkeley-based Arhoolie Records. In 1965, she toured with the American Folk Blues Festival in Europe, where her success was notable "because very few female blues singers at that time had ever enjoyed success across the Atlantic." While in England that year, she recorded her first album for Arhoolie, "Big Mama Thornton – In Europe". It featured backing by blues veterans Buddy Guy (guitar), Fred Below (drums), Eddie Boyd (keyboards), Jimmy Lee Robinson (bass), and Walter "Shakey" Horton (harmonica), except for three songs on which Fred McDowell provided acoustic slide guitar.
