If you’re reading this, you’re on the fence about seeing Corrosion of Conformity play the 9:30 Club tonight. On the fence is a pretty bad place to be when it comes to this band—you’re either going to love the combination of mid-’90s nostalgia and faint throbbing in your brain stem that their classic-rock-tinged metal induces, or you’re going to hate your life for a couple of hours. And make no mistake: This tour is being touted as a live revisit of their classic 1994 album Deliverance—the tour flyer features that album’s cover, plus the “hint,” in all-caps at the top: DELIVERANCE * REVIVAL * THROWDOWN * NORTH AMERICA 2015. It’s about as subtle as the band’s loud, sludgy sound. Lead singer and guitarist Pepper Keenan is back with group for the first time since 2006, and it’s the first time the original lineup has been together since 2001. Brant Bjork and The Low Desert Punk Band, Saviours, and Mothership open, but you’re there to see and hear Deliverance. Leather wrist cuffs, cutoff black T-shirt, and lank hair optional. How does it feel to be off the fence and swinging around the pit? Corrosion of Conformity performs with Brant Bjork and The Low Desert Punk Band, Saviours, and Mothership at 7 p.m. at 9:30 Club, 815 V St. NW. $20. (202) 265-0930. 930.com.
