Treasure Isle Studio Band The Supersonics were formed by Tommy McCook after The Skatalites split up due to Don Drummond' murdering his girlfriend in 1965. McCook left Studio One and joined Arthur "Duke" Reids' label Treasure Isle. Members were old partners from The Skatalites times and a bunch of new musicians. They were one of Jamaica's most productive studio backing bands. Releases are credited to them or to The Supersonics. Tommy led them until they disintegrated on a trip to Montreal Canada in 1969.
