"Wedding, March, Flower" will appear on the band's Miracle-Level album with earlier singles "Sit Down, Let Me Tell You a Story." and "My Lovely Cat!", and sees drummer Greg Saunier and lead vocalist Satomi Matsuzaki swap roles, with Saunier singing Matsuzaki's Japanese lyrics.

Saunier says, "I was flirting with my partner Sophie and sent her a video of me humming and playing the piano. Deerhoof was starting to get songs together for our next record. No one had suggested we needed any tender piano ballads, but Sophie convinced me to show it to my bandmates anyway. I was so touched when they were into it. The real kicker came when Satomi wrote lyrics. They were in Japanese, so when we first rehearsed it, I wasn’t even sure what I was singing. But Satomi had written a love song about a wedding. Satomi and I ended our marriage over 10 years ago, and it hasn’t always been easy for any of us to keep the band going. Our songs have always been one way that we all process our feelings with each other. Co-writing and performing "Wedding, March, Flower" with her was really intense."

Miracle-Level will be Deerhoof's 19th album, and first that sees Matsuzaki sing in her native Japanese language. The album was recorded over the space of two weeks in July 2022 with producer Mike Bridavsky, and also marks the group's first to be recorded in a proper studio.
