Lazers Do come when their American friends nestle against their Jamaican counterparts: Amanda Blank answers slack rapper Einstein with an equally filthy rhyme on "What U Like"; Brooklyn singer Jah Dan kicks a conscious flow on "Cash Flow"; and criminally underrated harmony sisters Nina Sky sing coquettishly on "Keep It Goin'." Sometimes it's difficult to appreciate our bouncement artists until you hear them hold their own with their Jamaican counterparts, like when Santogold chants a hook for Mr. Lexx's gruff war chant on "Hold the Line." It's then that you realize that club music's lingua franca — swagger, sex, and having fun — has no borders.

Meanwhile, the cover art for Guns Don't Kill People ... Lazers Do pays homage to the comic art found on the back covers of old Jamaican albums like Scientist Meets the Space Invaders (Greensleeves, 1981) and the Upsetters' Super Ape (Mob Entertainment, 2006). "Major Lazer is basically a fictional character we dreamt up to give this whole project we did down in Jamaica an identity, rather than it just being me and Wes — two white guys going down to Jamaica and trying to make a record," Switch says. "We tried to make it a little more fun."
