The Smiths, original Genesis, Talking Heads, Love Pentagon … You’ll be able to scratch that last one off your reunion wish list on Saturday, when the female five-piece at the forefront of the Vegas indie scene’s halcyon mid-2000s gets back together for one night only. All five members of the high-energy, surfy, electro-flecked rock group will be onstage—Christina Usatenko (vocals), Amanda Morgan (guitar), Judi Brown (bass), Marites Velasquez (keyboards) and Courtney Carroll (drums)—no logistical cinch considering Usatenko and Velasquez now live in Chicago, and Brown calls San Francisco home. But a chance Velveteen Rabbit meeting between Carroll and Velasquez led to a jam session earlier this year, during which Love Pentagon songs—from the group’s 2007 debut album Bang and its intended follow-up—were revisited, and an idea was hatched.

“Marites, Judi and Christina all have parents here … and the 4th of July weekend seemed like a good time to try to get everybody together,” Carroll says, explaining that everyone jumped on board once the prospect was floated. The Pentagon players were set to practice Wednesday, Thursday and Friday in preparation for the show, their first since 2009. Carroll reveals that she and Velasquez have even worked up some new material, which the band might debut Saturday. And after that? Carroll isn’t quite ready to call it a one-off. “Maybe we’ll go to Chicago and do it again there next year, and then maybe we’ll do San Francisco …”
