Party-starting masters and bashment bosses The Heatwave return for more glorious Carnival mayhem – on a truck. The crew will be launching their Carnival campaign with plenty of dancehall, ragga, soca, bass, bashment and rum cocktails, plus they've giving away free whistles and horns, the crazy fools. And did we mention they're bringing an actual truck into KOKO for full Carnival float vibes? An actual flipping truck, in a club. Carnival innit.
