Fear is the first of Cale's three studio albums for Island Records, all of which were released in a period of just over a year. During this time Cale was also producing records for other artists, working on albums such as Horses (1975) by Patti Smith, one of the most influential of all proto-punk records. In addition to his lead vocals on Fear, Cale also played keyboards, guitars, viola, violin and bass, and was joined by Fairport Convention's Richard Thompson, Roxy Music's Brian Eno and Phil Manzanera, and other artists who were signed to Island at the time. "Gun" features an unusual two-man guitar solo from Manzanera and Eno, with the latter using a synthesizer to process the former's guitar playing in real-time.
