Amidst a flurry of activity from Arcade Fire, multi-instrumentalist Will Butler has announced his departure from the group. In a Twitter thread posted on Saturday, the brother of frontman Win Butler revealed he left the band at the end of 2021.

Will wrote on Twitter,

Hi friends—
I’ve left Arcade Fire.

I left at the end of last year, after the new record was complete. There was no acute reason beyond that I’ve changed—and the band has changed—over the last almost 20 years. Time for new things.

I’m working on a new record; booking some shows this summer. I’m working on music for a David Adjmi play (which is so good). A few other projects percolating.

[…] Thank you to anyone who’s come out to AF shows, or bought a record, or loves our music. It’s meaningful to be part of your lives. Thank you to the crew, staff, management, label people, bands, artists, and friends who have helped bring our vision to life for so many years.

The band are still my friends and family.

Will joined the Canadian indie-rock band in 2003 two years after his brother Win formed it with his wife Régine Chassagne. The group has recently emerged from dormancy, detailing its first album since 2017, We, and releasing the first single, “The Lightning, I, II”, last week. Arcade Fire also staged a pair of surprise shows at New York’s Bowery Ballroom over the weekend. Dan Boeckner (Wolf Parade) filled in for Will during these recent performances.
