Itchy-O, a costumed collective of avant-garde percussion wizards, are titans of the Denver music scene whose fan base spreads from here to Tasmania, where they were centerpiece performers at the DARK MOFO Festival in Hobart. The band, which also shared bills with David Byrne & St. Vincent, Beats Antique and Devo, has been hard at work on the followup to 2014’s Burn the Navigator, and the results are finally here. Itchy-O’s latest work, From the Overflowing, is being released on September 7 by tastemaker label Alternative Tentacles. For those who can’t wait that long, the group will be holding court at the Gothic Theatre, 3263 South Broadway in Englewood, at 8 p.m. on Saturday, August 26, to perform songs off From the Overflowing after a rousing performance from vacation-rocking opening act SPELLS. Tickets are $20 in advance and $30 at the door. Visit itchyo.com — soon — to get yours.
