Luther Monroe Perkins (January 8, 1928 – August 5, 1968) was an American country music guitarist and a member of the Tennessee Three, the backup band for singer Johnny Cash. Perkins was an iconic figure in what would become known as rockabilly music. His creatively simple, sparsely embellished, rhythmic use of Fender Esquire, Jazzmaster and Jaguar guitars is credited for creating Cash's signature "boom-chicka-boom" style.
