Vampire Weekend bandmember and producer Rostam Batmanglij will debut his first film score at The Sundance Film Festival in the drama Sound of My Voice, which was written and directed by his brother Zal Batmanglij.

The film, which according to Pitchfork (via Playlist) centers on a couple of cult-infiltrators in California, is Zal’s first feature-length production. While little else is known about this indie, Rostam’s involvement could mean a soundtrack release. So Vampire Weekend fans should keep and ear out for updates.
