Errol Thompson, better known as "ET" (December 29, 1948 – November 13, 2004) was a record producer, audio engineer, one of the first studio engineers to be involved in dub music. After engineering [apparently without Clement "Coxsone" Dodd's approval] Max Romeo's Wet Dream during his apprenticeship under Sylvan Morris at Studio One, he joined Vincent "Randy" Chin's operation for countless forays into dub on the Impact! and Randy's labels and later established a successful partnership with Joe Gibbs as one half of Mighty Two, with his E.T. Recording Studio within Joe Gibbs Studio facilities.
