James Gang was an American rock band formed in Cleveland, Ohio in 1966. The band went through a variety of line-up changes until they recorded their first album as a power trio consisting of Joe Walsh, Tom Kriss (bass) and Jim Fox (drums). Dale Peters replaced Kriss on bass for the band's second and third albums. Two of the band's songs, "Funk #49" and "Walk Away", continue to be popular on classic rock and AOR stations.

A power trio is a rock band format that has a three-musician lineup of electric guitar, bass guitar and drum kit. It leaves out a fourth member, dedicated vocalist, and an additional rhythm guitar or keyboard instrument that are often used in other rock bands such as quartets and quintets. Notable examples of power trios include ZZ Top, Nirvana, the Jimi Hendrix Experience, Motörhead, Grand Funk Railroad, the Police, Rush, Cream, Blink-182 and Green Day.
