The Replacements are an American punk rock band formed in Minneapolis, Minnesota in 1979, and are considered pioneers of alternative rock. The band was composed of guitarist and vocalist Paul Westerberg, guitarist Bob Stinson, bassist Tommy Stinson, and drummer Chris Mars for most of their career. Following several critically acclaimed albums, including Let It Be and Tim, Bob Stinson left the band in 1986 and the band experienced several line-up changes; Slim Dunlap joined as lead guitarist and Steve Foley replaced Chris Mars in 1990. Towards the end of the band's career, Westerberg exerted more control over their creative output. The group disbanded in 1991, with the members ultimately pursuing various projects. However, a reunion was announced on October 3, 2012. The Replacements never experienced any significant commercial success but have influenced a variety of alternative rock acts.
