[Editor's note: Cinemechanica was removed from this bill after press time.]

While the world continues to wait patiently for local math-rock legends Cinemechanica to release their long-promised followup to 2006's The Martial Arts—reportedly "coming soon" but, like, I'll believe it when I hear it—the band has at least ramped up its live activity in recent months. Tighter and louder than ever, the group headlines Caledonia Friday, when local faves Muuy Biien and virtuosic North Carolina duo The Bronzed Chorus will also appear. And please don't miss Trioscapes, a soul-stirring post-prog trio whose recent, sax-laden Digital Dream Sequence showcases a young group firmly in charge of its sound, no matter how unwieldy it seems at times.

9:30 p.m. $7 (21+), $9 (18–20). www.caledonialounge.com
