The Replacements were an American rock band formed in Minneapolis, Minnesota, in 1979 after nineteen-year-old Bob Stinson gifted his eleven-year-old brother Tommy Stinson a bass guitar. The band was composed of the guitarist and vocalist Paul Westerberg, guitarist Bob Stinson, bass guitarist Tommy Stinson, and drummer Chris Mars for most of its existence. After two albums in the style of punk rock, they became one of the main pioneers of alternative rock with their acclaimed albums Let It Be and Tim. Bob Stinson was kicked out of the band in 1986, and Slim Dunlap joined as lead guitarist. Steve Foley replaced Mars in 1990. Towards the end of the band's career, Westerberg exerted more control over its creative output. The group disbanded in 1991 and the members eventually found various projects. A reunion was announced on October 3, 2012. Fans affectionately refer to the band as the 'Mats, a nickname which originated as a truncation of "The Placemats".
