As soon as you try to grasp The Bug’s latest, London Zoo, it careens off in unexpected directions, with beats, lyrics, reverb, and bass recreating themselves in endless new permutations with each consecutive track. By refusing to be nailed to one genre, The Bug has created a blazing, blistering document that’s true to the bass ethic while smashing its boundaries. Is it dancehall? The Tippa Irie-voiced “Angry” might sway you in that direction. Is it dubstep or grime? Sure, “Poison Dart” and “Skeng” were legitimate hits in those scenes, but only because their brutal sonics sounded nothing like other dubstep tunes. With London Zoo, The Bug hits his stride.
