Yesterday (18 February), Big Thief shared a video of Adrianne Lenker performing new song "Simulation Swarm" on a acoustic guitar via their Instagram.

The band revealed the video was recorded in March 2020, and that they're "still working on this one".

"Simulation Swarm" is yet to get an official release, but it'll follow the band's various demos and outtakes that they released last year following their two 2019 albums U.F.O.F. and Two Hands.

Although Big Thief are yet to release new music this year, many of the band members have been focused on solo material. Lenker released her companion solo albums Songs and Instrumentals in October last year, guitarist Buck Meek unveiled his second solo album Two Saviors just last month, and Big Thief's drummer James Krivchenia released his A New Found Relaxation album in June 2020.

In September last year, Big Thief contributed a demo of "Jane" to the To the People of the Land: Carrizo​/​Comecrudo Solidarity Compilation.
