New York rock searchers Yeasayer haven’t released a new album since 2012’s Fragrant World, but they have now broken their silence. Last month, the band started posting mysterious teasers for what sure seems to be a new album, possibly titled Amen & Goodbye. And now, a new single called “I Am Chemistry” has appeared. The song is a churning groove that packs a whole lot into its five minutes: A percussive rhythmic base, a proggy synth excursion, and what sounds like a children’s choir singing over a florid piano. Listen to the song below. The album will be out in April.
