The Final Solution (also known as Earth Mother and the Final Solution) was an American garage rock band formed in San Francisco, California, in 1965. An early group in the development of what later became known as the San Francisco Sound, the Final Solution contradicted its contemporaries with their controversial name and grim lyrics composed by lead guitarist Ernie Fosselius and bassist Bob Knickerbocker. Although the group never released any recordings in their career, the band was pivotal in the San Francisco's live music scene. A recording of the Final Solution performing at the Matrix in 1966 exists and is available, particularly "So Long Goodbye", which appears on Pebbles, Volume 22.
