"Siberian Butterfly" lands after earlier singles "Forecast of Rain" and "American Crisis".

Mould has also shared a statement to go with the track, "The genesis of "Siberian Butterfly" spoke to the notion of "collectors" - people with excessive means who gather the works of creative folk for their ego-driven portfolios. As I kept writing, the narrative shifted toward themes of change, growth, and freedom. These motifs are central to how we become our true selves. This is how we begin our journey toward our true identities."

He continues, "It’s autobiographical as well. I put myself through some self-hating years as a young gay man - never feeling "good enough", not recognising the positive qualities I had to offer, while inhibiting the development of my gay identity. I hope for a world where all people can be what they want to be. Life seems shorter every day; maybe this simple song can be of use to people who are struggling to find their true selves."

Blue Hearts will follow on from Mould's 2019 LP Sunshine Rock. The new album was produced by Mould at Chicago’s Electrical Audio with longtime collaborator Beau Sorenson engineering.

Of his forthcoming album, Mould explains, "We have a charismatic, telegenic, say-anything leader being propped up by evangelicals. These fuckers tried to kill me once. They didn’t do it. They scared me. I didn’t do enough. Guess what? I’m back, and we’re back here again. And I’m not going to sit quietly this time and worry about alienating anyone."
