Trade originated as an underground club night beneath Turnmills pub in Clerkenwell Road. Trade was the second nightclub Laurence had run at Turnmills; his first was Xanadu, which he co-hosted with the club promoter Robert Pereno. Laurence was a member of the electronic music duo Big Bang when he opened Trade. The history of Trade is inextricably linked with the evolution of Turnmills as a club venue. Xanadu opened in early-1990 and ran on Saturday evenings from 10.00 pm to 2.30 am.
