As a multi-instrumentalist and producer for Vampire Weekend, Rostam Batmanglij shaped the eclectic indie rockers’ sound as much as frontman Ezra Koenig. Since leaving the group in early 2016, Batmanglij has produced tracks for Frank Ocean, Solange, and Haim. Released last September, his first solo album, Half-Light, is an LP of warm, quietly intricate indie-pop beauty that’s lyrically predicated on his identity as a gay Israeli-American born to immigrant parents.
