Sunn O))) are currently working on a new album.

The news broke via a rather nice newsletter from Stephen O'Malley and Greg Anderson:

"O))) are working on three new tours in both US and EU and also will be continuing work on a brand new SUNN O))) album across the span of 015. We are looking forward to unleash to the masses."

If the thought of waiting is too much to take, we recommend revisiting their collaborative album with Scott Walker.
