The Jimi Hendrix Experience was an American-English rock band that formed in Westminster, London, in September 1966. Singer, songwriter, and guitarist Jimi Hendrix, bassist and backing vocalist Noel Redding, and drummer Mitch Mitchell comprised the group, which was active until June 1969. During this time, they released three studio albums and became one of the most popular acts in rock. In April 1970, Hendrix, Mitchell, and bassist Billy Cox performed and recorded until Hendrix's death on September 18, 1970. This later trio was sometimes billed as the "Jimi Hendrix Experience", but the title was never formalized.
