The stage setups for Grammy performances are often extravagant and imaginative, like Daft Punk's Alien-inspired set from last night's awards, but sometimes they're just extravagant. Watch the very literal performance of Katy Perry and Juicy J's "Dark Horse" above.
Taking the song's line, "so you want to play with magic" at face value, Perry acted as an enchantress, emerging from a crystal ball clad in seductive, witchy garb. The close-reading of the lyrics to "Dark Horse" continued when, lo and behold, a group of men disguised as an actual dark horse appeared onstage. Clearly, depicting the idiomatic meaning of that phrase would have been too abstract for "Music's Biggest Night." Thankfully, when Juicy J stepped onstage to perform his verse, none of what he said (including "She eats your heart out like Jeffrey Dahmer" and "I’m gon’ put her in a coma") was recreated onstage.
