A’caween 2015: Local a cappella powerhouses Faces for Radio and The Uptones return to the High-Hat for a cheerful celebration of the macabre, all told in song.

Kick off the trick-or-treat festivities with your favorite tunes dressed up in costumes of talented vocal stylings, intricate harmonies and shape-shifting arrangements. No instruments need apply.

And since it’s Halloween, there will be spectacle, bad monster jokes, and — of course — candy.

Show starts at 9pm, $10 cover. 21+. Costumes admired but not required.
