Feedback is the fifth album by the rock band Spirit. Released in 1972, it was the first Spirit album without original members Jay Ferguson and Mark Andes, and it was also the only Spirit album that did not feature Randy California performing on it, as California had left the group to pursue a solo career.
Feedback was the only Spirit album to feature John and Al Staehely as band members. Musically it was a different turn for the band, in favor of a country influenced hard rock style and lyrics mostly dealing with conventional male-female love topics, with only the tracks "Darkness" and the instrumentals "Puesta Del Scam" and "Trancas Fog-Out" recalling Spirit's earlier psychedelic rock. Although the album wasn't widely heard in later years, it has finally surfaced on CD and has received some extremely satisfying notices. The Feedback tour saw the remaining original members (Locke and Cassidy) leave the band during the tour, and Chris and Al Staehely regrouped the band under a new name, Sta-Hay-Lee, recording another album self-titled under the Sta-Hay-Lee name in 1972. Chris Staehely would later join Jay Ferguson's band Jo Jo Gunne.
Al Staehely, already a lawyer at the time, went on to become a full-time entertainment lawyer.
