If the phrase “family-friendly festival” induces a series of yawns and “mehs” from you and yours, consider the gauntlet thrown. Hot Water Hills Music & Arts Festival, the pop-up arts weekend that comes to Hill Wheatley Plaza in Hot Springs every year courtesy of Low Key Arts, announced the festival’s closing act yesterday, and it’s a zinger.

Itchy-O, the 40+ member percussion and performance art group with whom David Byrne and St. Vincent closed out a 2013 show at Chatfield Botanical Garden, plans to drop its second full-length album, “From the Overflowing” on September 7, and a month later, the band will close out the Hot Water Hills Festival, October 6-7.

Here’s what a band member had to say about the group’s performance ethos, in an interview with Colorado Daily in 2014:

Our goal is chaos, and we rock the Church of Entropy. However, the music itself is highly structured and organized. But, one of the things that is so disorienting about an itchy-O show is that we smash this perception that the band plays on stage. Audiences are so conditioned to focusing their attention toward the front of the house that when performers come up from behind them and play next to them, that division that is broken is really powerful. People then feel overcome by the show and even be a part of.

Last Thursday morning, the band dropped its very first music video, a collaboration  with Austin-based filmmaker Joe Nicolosi.

Hot Water Hills takes place October 6-7 at Hill Wheatley Plaza in Hot Springs, 629 Central Ave. Weekend passes are available on Prekindle here, $15, and tickets for kids 12 and under are free.
