Have you ever thought about the multiverse, or simply what could have been? As Lanterns on the Lake detail in their newest single, "String Theory," there can be beauty — and solace — in the unknown.

"I saw this thing last night/ About the multiverse/ And so the theory goes/ There's more than one of us/ Oh my God, I could have cried/ Oh my God, I hope they're right," the indie rock band's frontwoman Hazel Wilde sings.

In this episode of Press Play, Lanterns on the Lake perform the track in an empty church, intensifying the existential introspection of "String Theory." As Wilde leads the performance with soaring vocals, her bandmates add to the performance's power with electric guitars, drums and violin.

"String Theory" is the second single from Lanterns on the Lake's forthcoming album, Versions of Us, out June 2 via Bella Union. Radiohead's drummer, Philip Selway, played drums on the entire album, and he joins the band on a second drum set in this Press Play performance.

Reflecting on the LP, Wilde revealed that the new music will largely be about the multiverse phenomenon discussed in their latest song. "I've got to believe that there's a better way and an alternative one we've been hurtling towards," she says. "I've also got to believe that I could be better as a person, too."
