The Calm Blue Sea @ Mohawk on Jan 6, 2012

There's a violence to The Calm Blue Sea's music, one built on crescendos and tension and crash symbols that throw their weight around like at tidal wave ripping about in the middle of the Atlantic Ocean. Headlining a night of post-rock that included Missions and Clouds are Ghosts on the penultimate evening of Free Week, the quartet channeled a powerful fury on each of their extended, highly orchestrated instrumental tracks.
