The Doors, one of the most influential and controversial rock bands of the 1960s, were formed in Los Angeles in 1965 by students Ray Manzarek, keyboards, and Jim Morrison, vocals; with drummer John Densmore and guitarist Robby Krieger. The group never added a bass player, and their sound was dominated by Manzarek's electric organ work and Morrison's deep, sonorous voice, with which he sang and intoned his highly poetic lyrics.
