October 1. Prior to playing their first gig, in 2010, the members of Radkey had actually been together for a few years—they're brothers, after all. Isaiah (bass), Solomon (drums), and Dee Radke (vocals and guitar) formed the band in their native St. Joseph, Missouri, and it didn't take long for social media to start blowing up over the concept of a trio of home-schooled, mixed-race Midwestern siblings playing energetic punk rock. But instead of signing up with dollar-sign-seeing Hollywood handlers, Radkey, who kick off Rocktober with this show at the Half Moon, remain under their dad's management and have risen to the "just a novelty act" challenge by hitting it head-on—and hitting it on the head—via the title track and the hard-rocking balance of their new debut album, Dark Black Makeup. With Donkey Song. (Best Girl Athlete and Chris Garneau play October 16; Javelin hits the target October 10.) 8pm. $7. Hudson. (518) 828-1562. Thehalfmoonhudson.com.
