Kim Shattuck, the frontwoman and guitarist for Southern California punk trio The Muffs who also played with ’80s rockers The Pandoras and took a brief turn as the Pixies’ post-Kim Deal bassist, died on Wednesday from complications of ALS, her family and bandmates announced.

She was 56.

In a statement on Facebook, her Muffs bandmates Ronnie Barnett and Roy McDonald wrote, “Besides being a brilliant songwriter, rocking guitarist and singer/screamer extrodinaire, Kim was a true force of nature. While battling ALS Kim produced our last album, overseeing every part of the record from tracking to artwork. She was our best friend and playing her songs was an honor.”

Shattuck played bass in The Pandoras, an all-women band that emerged from the Hollywood garage-rock scene before taking a turn toward harder rock, from 1985 to 1990. Following that, she formed The Muffs, who scored some airplay with 1995 college-radio hit “Sad Tomorrow” and a cover of Kim Wilde’s “Kids in America” from the soundtrack to “Clueless.”

While still in The Muffs, Shattuck was enlisted by the Pixies to handle bass duties in 2013 following the departure of Deal, but, following a European tour with the band, she was fired.  “Super disappointed to learn that my time with the Pixies ended today,” she wrote on social media at the time.

The Muffs are scheduled to release what presumably will be their final album, No Holiday, on Oct. 18.
