The Flock was an American rock band formed in Chicago in 1966, known for their innovative fusion of rock, jazz, and classical music elements. Led by violinist Jerry Goodman, the band gained prominence in the late 1960s and early 1970s with their virtuosic instrumental performances and the hit single "Tired of Waiting for You." Their experimental approach to rock music made them pioneers of progressive rock and a beloved fixture of the psychedelic era before disbanding in 1971.
