State Theatre and Waterville Opera House present The Ghost of Paul Revere at 8 p.m. Saturday, Dec. 29, at the Waterville Opera House, 1 Common St. in Waterville.

This Portland-based band describes their sound as “holler folk,” not because it involves a lot of hollering, per se, but because it invokes the rich communal tradition of field hollers, with their call-and-response melodies, sing-along hooks, and densely layered harmonies. That sense of musical camaraderie is essential to everything The Ghost of Paul Revere does, and nowhere is it more evident than their sophomore album, “Monarch.’

The opening act will be Bella’s Bartok. To understand Bella’s Bartok, imagine what you would get if Salvador Dali and Toulouse Lautrec were fronting the Moulin Rouge’s house band, and you have the exuberant spectacle that is Bella’s Bartok. Described as “about as much fun as you can have with your pants on” (Dan Wolovick, Two Way Monologues), this 6-piece powerhouse melds Bohemian Klezmer Punk with pop sensibilities into an eminently danceable party. The diversity of musicians that make up Bella’s Bartok, combined with their boundless energy on stage, has been known to break a dancefloor, or two (or three, but who’s counting?).

Tickets cost $20 in advance or $25 day of show.
