Via their Darkness Day Facebook event page Surly announces their newest beer, Damien.

From the page-

What's Damien you ask? Here's the official description from head brewer Todd Haug: From the blackest depths of the brewhouse comes Damien, Child of Darkness. Spawned from the usually discarded remnants of Darkness, Damien is a dry-hopped black ale. Flavors of roasted malt and dark brown sugar suffocated by aromas of tangerine and pine. 35 IBUs, 5% ABV.

I can't wait to try some.
