Head East was a hard rock quintet originally from south central Illinois, then Champaign, Illinois, USA. They released their first album, Flat as a Pancake, in 1974 on their own record label (Pyramid Records) selling all 5,000 records and 500 eight-tracks produced. A&M was impressed enough to sign the band and re-release the album in 1975 which went gold by 1978.
These are photos from concerts where Head East played, so they may be of other bands that played the concert as well.
