The Flock was an American, Chicago-based jazz rock band, that released two albums on Columbia Records in 1969 (The Flock) and 1970 (Dinosaur Swamps). The Flock did not achieve the commercial success of other Columbia jazz-rock groups of the era such as Chicago and Blood Sweat & Tears, but were recognized for featuring a violin prominently in their recordings. The violinist, Jerry Goodman, went on to become a member of Mahavishnu Orchestra and a solo artist.
