Earn a hangover with The Mapes

It promises to be almost fun as an open bar — until the next morning hits like a thunderstorm of anvils. Earn a gnarly hangover the right way with Vegas punks The Mapes, who surely will delight in putting the “turd” in Saturday, along with fellow ragers 1/2 Ast, hard-core cover band Dick Falcon and San Fran’s LA Plebe. Just make sure to have the Pepto Bismol within arm’s reach, dudes.
