Colin L. Orchestra + Opsvik and Jennings + Alan Watts

A former member of local prog-punk favorites the USA Is a Monster, Colin Langenus now helms a dreamy, jammy eponymous ensemble—probably the closest he'll ever get to conventional singer-songwriterdom but still plenty eccentric. Tonight Langenus celebrates a riotously sprawling new double album, Infinite Ease/Good God (Northern Spy), in the company of songful jazzers and improvising rockers.
