A tribute act is a music group, singer, or musician who specifically plays the music of a well-known music act, often one which has isbanded or ceased touring. Probably the largest class of tributes acts are Elvis impersonators, individual performers who mimic the songs and style of Elvis Presley; however, most tribute acts are groups (tribute band or tribute group) and are tributes to a group. For example The Iron Maidens are an all female band that pays tribute to Iron Maiden. A tribute band rarely includes any members of the original band whose music is being honored, although guest appearances do occur. For example former Bruce Springsteen drummer Vini Lopez often plays sets with the Springsteen tribute band The E Street Shuffle.
