Sewer Trout was an American punk rock band, formed in Sacramento, California in 1985. The group's uptempo bass lines and fast-paced songs would serve as a basis and influence for many of the later California pop punk bands of the 1990s. The band consisted of Jim MacLean (lead vocals/bass), his brother Hal MacLean (drums), and Keith Lehtinen (guitar/backing vocals), with Erik Benson joining as a second guitarist after meeting Hal at Sacramento State.
