RIP Ray Collins, Mothers of Invention singer, 75

[Wayback]

Collins was critical to the Mother's early sound and sang on the band's first four albums. He fired the group's first guitarist and replaced him with Frank Zappa. Collins left the band in 1968, unhappy with the group's direction toward satire.
