Le Sony’r Ra (born Herman Poole Blount, May 22, 1914-May 30, 1993), better known as Sun Ra, was an American jazz composer, bandleader, piano and synthesizer player, and poet known for his experimental music, “cosmic” philosophy, prolific output, and theatrical performances. For much of his career, Ra led the “Arkestra”, an ensemble with an ever-changing name and flexible line-up. Born and raised in Alabama, Blount became involved in the Chicago jazz scene during the late 1940s. He soon abandoned his birth name, taking the name Le Sony’r Ra, shortened to Sun Ra (after Ra, the Egyptian god of the Sun). Claiming to be an alien from Satun on a mission to preach peack, he developed a mythical persona and an idiosyncratic credo that made him a pioeer of Afrofuturism. Throughout his life he denied ties to his prior identity saying, “Any name that I use other than Ra is a pseudonym”. His widely eclectic and avan-garde music echoed the entire history of jazz, from ragtime and early New Orleans hot jazz, to swing music, bebop, free jazz and fusion. His compositions ranged from keyboard solos to works for big bands of over 30 musicians, along with electronic excursions, songs, chants, percussion pieces, and anthems.Sound of Joy is an album by Sun Ra and his Arkestra. It features the Arkestral lineup during the last few months of 1956, after trombonist Julian Priester left to join Lionel Hampton, Charles Davis became a regular member of the band, and Victor Sproles took over on bass. It was intended as the follow-up to Jazz by Sun Ra but Transition Records ceased to operate before it could be released. Four of the tracks were included on Sun Ra and his Solar Arkestra Visits Planet Earth, released in 1966. The entire LP was eventually released in 1968 by Delmark Records, who also re-issued Jazz by Sun Ra. Two ballads, written by Sun Ra and sung by Clyde Williams, were left off the original album, however, because the president of Delmark Records, Bob Koester, "felt they didn't fit with the other pieces on the session." The songs were reinstated when the album was re-issued on CD in 1994.
