Kim Shattuck formed the Muffs with bassist Ronnie Barnett, drummer Criss Crass and Melanie Vammen. After two singles for indie labels Sub Pop and Sympathy for the Record Industry, which generated a large underground buzz, the Muffs were picked up by Warner Bros and subsequently released their powerful eponymous debut album in 1993. Shortly after, Crass left the group and was replaced temporarily by drummer Jim Laspesa for the tour.

After switching to Reprise Records in 1995 and after a year of touring in venues throughout the world, the Muffs headed back into the studio to record the follow-up, Blonder and Blonder; now a three-piece due to Vammen's departure.

Right before recording Blonder and Blonder, ex- Redd Kross drummer and longtime Muffs friend Roy McDonald joined the group. Happy Birthday to Me followed in 1997 and two years later Alert Today, Alive Tomorrow was released by Fat Wreckords; a rarities collection, Hamburger, appeared in early 2000 on Sympathy for the Record Industry.

The Muffs released their new CD Really Really Happy on Five Foot Two Records during the summer 2004 and toured the US and Japan later that year.

January 2005 The Muffs released a limited edition LP of Really Really Happy on Sympathy for the Record Industry.

In September 2005 The Muffs were featured in a series of Canadian Milk commercials that played throughout Canada.

Throughout 2006 The Muffs will be writing and recording a new album. Look for The Muffs playing random shows here and there to try out new material.
