Yesterday in a shocking announcement, Vampire Weekend songwriter and producer Rostam Batmanglij announced on Twitter that he has left the band. In the post below, he says that though he and Ezra Koenig will continue to collaborate, "my identity as a songwriter and producer needs to stand on its own."

Vampire Weekend's last album was 2013's Modern Vampires of the City, although Rostam recently put out a new solo single called "EOS."
