The Mothers of Invention

The Mothers of Invention (also known as the Mothers) was an American rock band from Pomona, California. Formed on May 9, 1965, their work is marked by the use of sonic experimentation, innovative album art, and elaborate live shows. Originally an R&B band called the Soul Giants, the band's first lineup comprised Ray Collins, David Coronado, Ray Hunt, Roy Estrada, and Jimmy Carl Black. Frank Zappa was asked to take over as the guitarist when a fight between Collins and Hunt led to the latter's being fired.
