"This was written at a cottage in the English countryside in winter where we had gone on a writing retreat to escape the noise of London," the Staves' Jessica and Camilla Staveley say of their new song, "Sitting By the Fire," out today. "On a cigarette break, Jessica went outside in the dark and could see Camilla through the window, sat at the fireplace writing a song. The song is a photograph of sorts, capturing that moment. We recorded this after we had cut the record [All Now] out in LA. We were back in London and revisited this tune and we felt that it would really be perfect to have [our sister] Emily join us on it to lend her voice to this a cappella recording."

The Staves' new EP Happy New Year, out today, includes three acoustic versions of tracks from their new album, All Now—"I Don't Say It, But I Feel It," "After School," and "All Now"—and a cover of The Beatles' "She's Leaving Home." Also out now: an acoustic performance video for "After School," which the duo calls "a love song to our sister Emily inspired by the bands we were listening to in the '90s. Putting on the rose-tinted glasses and embracing nostalgia."
