Mainstream Records was an American indie record label, which released jazz, rock music, and soundtracks during the 1970s.
It was founded in 1964 by Bob Shad, and in its early history reissued material from Commodore Records and Time Records in addition to some new jazz material. The label released Big Brother & the Holding Company's first material in 1967, as well as The Amboy Dukes' first albums, whose guitarist, Ted Nugent, would become a successful solo artist in the 1970s. Mainstream acted as the distributing label for Bob Thiele's Flying Dutchman Records and continued issuing soundtracks and new jazz material through to 1978, when it ceased.
