Their third album from 1983. Described by producer Adrian Sherwood as: "Experiments in active frequencies, out of time noises, rhythms within rhythms, and endless tape edits (edits on edits) resulting in the ultimate cut-up and paste job..." whilst an On-U press release of the time declared: "A high-tech rhythm mix of human, animal and machine sounds, captured on the Southern Studios digital rig by the "wackid' mixer ADRIAN SHERWOOD, up in sunny Wood Green, DRASTIC SEASON features that On-U rugged bass sound. Check it if you're a dancer, a listener, a film maker, a computer programmer, a human or an animal. Special treats in store for steam locomotive enthusiasts and biologists.
