The Muffs are an American punk rock band based in Southern California, formed in 1991. Led by singer and guitarist Kim Shattuck, the band released four full-length studio albums in the 1990s, as well as numerous singles including “Lucky Guy” and “Sad Tomorrow”, and a cover version of “Kids in America”. After a long hiatus beginning in 1999, the band released a fifth album in 2004 but thereafter effectively disbanded. Almost a decade later, the three core members of the band reunited and started performing again. An album, Whoop Dee Doo, was released in 2014.
