Metro Boomin has one of the best drops in hip-hop—a threatening seal of approval from frequent collaborator Future. When you hear it, you know what to expect: dense, heavy low-end; eerie synth loops and layered drum programming that still catches you by surprise. The St Louis native threw down the gauntlet with the whirlwind beat for Future's "Karate Chop", and the bone-chilling “Jumpman” delivers on that promise.
