Sometimes a pun can be taken too far. Far too far. But other times, said adventurous pun is surprisingly appropriate, as is the case with Dark Side of the Moonshine, the San Francisco-based Poor Man’s Whiskey bluegrass band’s performance of Pink Floyd’s classic album. Let’s just say that if you like your live music driven by an amalgamation of upbeat hootenanny bluegrass, concept album classic rock, and costumes of characters from The Wizard of Oz, you’ll want to be at the Iron Horse this Monday.

Having played The Great American Music Hall, the Telluride Bluegrass Festival and the legendary Fillmore Hall, Poor Man’s Whiskey makes a quick one-week stopover in the Northeast before heading back out West. Its Northampton appearance will include two sets, the first featuring the band’s original music, the second covering Pink Floyd’s Dark Side of the Moon, with bandmates dressed as characters from The Wizard of Oz.

The members include Sean Lehe on guitars, Aspen Stevenson on bass and vocals, George Smeltz on drums and—wait for it—suitcase, Jason Beard on guitar and mandolin, and Josh Brough—who makes a lovely bearded Dorothy—on vocals, harmonica, keyboards and banjo.

March 31, 7 p.m., $10/advance, $13/door, Iron Horse Music Hall, 20 Center St., Northampton, (413) 586-8686, iheg.com.
