School of Seven Bells multi-instrumentalist Benjamin Curtis lost his battle with T-cell Lymphoblastic Lymphoma, a rare type of non-Hodgkin lymphoma, on Sunday night.

An announcement was made on his band's Facebook page. It reads in part, "While we had hoped to delay this announcement until a more suitable time when his friends and family could feel better prepared and settled to greet any correspondences from folks attempting to reach out, unfortunately the news has prematurely leaked. So we felt it would be appropriate to at least offer an official acknowledgement from us, in light of all the fans who loved and supported Benjamin and his music."

According to OklahomaRock.com, Curtis, who was born in Oklahoma, passed away at a cancer center in New York City.

Curtis, who was 35, was diagnosed with cancer last year. Before launching School of Seven Bells, which released three studio albums and an EP, he served as a drummer for Tripping Daisy. He'd also joined his brother, Brandon, in the Secret Machines.
