Some say you should cue the music when the MGM lion roars. Others argue it’s the third roar, and some say it’s best when the screen fades to black, signaling the start of the first scene. We’re talking about the eerie synchronicity that occurs if you play the audio from Pink Floyd’s Dark Side of the Moon alongside 1939 classic film The Wizard of Oz. They refer to it as Dark Side of the Rainbow, and if you’ve never experienced the Scarecrow dancing down the yellow-brick road to “Brain Damage,” your chance comes Thursday night at the Bunkhouse.

Making for an even greater spectacle, the music will be performed live. Jersey Boys trumpeter Joey Pero and Vegas’ Pink Floyd cover band Is it Floyd? will take the stage for two performances, channeling Roger Waters and David Gilmour with full renditions of the beloved 1973 concept album while Dorothy and Toto make their trek to the Emerald City. Just be sure to let us know, is it the first roar, or the third?

Dark Side of the Rainbow December 11, 8 & 10 p.m., $10. Bunkhouse Saloon, 702-854-1414.
