The Ornette Coleman Double Quartet

In 1960, Coleman recorded Free Jazz: A Collective Improvisation, which featured a double quartet, including Cherry and Freddie Hubbard on trumpet, Eric Dolphy on bass clarinet, Haden and LaFaro on bass, and both Higgins and Blackwell on drums. The record was recorded in stereo, with a reed/brass/bass/Drums quartet isolated in each stereo channel. Free Jazz was, at nearly 40 minutes, the lengthiest recorded continuous jazz performance to date, and was instantly one of Coleman's most controversial albums.
