 The personalities associated with the subculture, gurus such as Timothy Leary and psychedelic rock musicians such as the Grateful Dead, Pink Floyd, Jimi Hendrix, The Byrds, The 13th Floor Elevators, Ultimate Spinach, Janis Joplin, Crosby, Stills & Nash, The Doors, Blue Cheer, The Chambers Brothers, Country Joe and the Fish, Big Brother and the Holding Company, Jefferson Airplane and the Beatles, soon attracted a great deal of publicity, generating further interest in LSD.The popularization of LSD outside of the medical world was hastened when individuals such as Ken Kesey participated in drug trials and liked what they saw.Tom Wolfe wrote a widely read account of these early days of LSD's entrance into the non-academic world in his book "The Electric Kool Aid Acid Test", which documented the cross-country, acid-fueled voyage of Ken Kesey and the Merry Pranksters on the psychedelic bus "Furthur" and the Pranksters' later "Acid Test" LSD parties.
