In late 1965, the members of The Warlocks discovered another band performing under their same name. With the help of a nearby dictionary of folklore, Jerry Garcia rechristened them Grateful Dead. Newly-named, the group became the house band for Ken Kesey’s Acid Tests. They went on to become one of the longest-performing rock bands around, with one of the most devoted fan bases of all time. Though the lineup changed over the band’s thirty-year tenure, the core remained mostly intact.
