Franklin Joseph Lymon (September 30, 1942 - February 27, 1968), known professionally as Frankie Lymon, was an American rock and roll/rhythm and blues singer and songwriter, best known as the boy soprano lead singer of the New York City-based early rock and roll group The Teenagers. The group was composed of five boys, all in their early to mid-teens. The original lineup of the Teenagers, an integrated group, included three African-American members, Frankie Lymon, Jimmy Merchant, and Sherman Garnes; and two Puerto Rican members, Joe Negroni and Herman Santiago. The Teenagers' first single, 1956's "Why Do Fools Fall in Love," was also its biggest hit.
In early 1957, Lymon and the Teenagers broke up while on a tour in Europe. During an engagement at the London Palladium, Goldner began pushing Lymon as a solo act, giving him solo spots in the show. Lymon began performing with backing from pre-recorded tapes. The group's last single, "Goody Goody" backed with "Creation of Love," initially retained the "Frankie Lymon & the Teenagers" credit, but they were actually solo recordings (with backing by session singers). Lymon had officially departed from the group by September 1957; an in-progress studio album called Frankie Lymon and the Teenagers at the London Palladium was instead issued as a Lymon solo release. As a solo artist, Lymon was not nearly as successful as he had been with the Teenagers. Beginning with his second solo release, "My Girl", Lymon had moved to Roulette Records. On a July 19, 1957 episode of Alan Freed's live ABC TV show The Big Beat, Lymon began dancing with a white teenage girl while he was performing. His actions caused a scandal, particularly among Southern TV station owners, and The Big Beat was subsequently canceled. There is no surviving footage because the episode was taped over, according to Judith Fisher Freed. Lymon's slowly declining sales fell sharply in the early 1960s. Within the span of one year, as a result of heroin use, and the deepening of his voice to a baritone as a result of going through puberty. His highest-charting solo hit was a cover of Bobby Day's "Little Bitty Pretty One", which peaked at No. 58 on the Hot 100 pop chart in 1960 and which had been recorded in 1957. Addicted to heroin since the age of 15, Lymon fell further into his habit, and his performing career went into decline. According to Lymon in an interview with Ebony magazine in 1967, he was first introduced to heroin when he was 15 by a woman twice his age. In 1961, Roulette, now run by Morris Levy, ended their contract with Lymon and he entered a drug rehabilitation program. After losing Lymon, the Teenagers went through a string of replacement singers, the first of whom was Billy Lobrano. In 1960, Howard Kenny Bobo sang lead on "Tonight's the Night" with the Teenagers; later that year, Johnny Houston sang lead on two songs. The Teenagers, who had been moved by Morris Levy to End Records, were released from their contract in 1961. The Teenagers briefly reunited with Lymon in 1965, without success.

Sun Ra (born Herman Poole Blount, legal name Le Sony'r Ra; May 22, 1914 - May 30, 1993) 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 eventually became involved in the Chicago jazz scene during the 1940s. He soon abandoned his birth name, taking the name Sun Ra (after Ra, the Egyptian God of the Sun) and developing a complex persona and mythology that would make him a pioneer of Afrofuturism: he claimed he was an alien from Saturn on a mission to preach peace, and throughout his life he consistently denied any ties to his prior identity.
After the move to New York, Sun Ra and company plunged headlong into the experimentalism that they had only hinted at in Chicago. The music was often extremely loud and the Arkestra grew to include multiple drummers and percussionists. In recordings of this era, Ra began to use new technologies--such as extensive use of tape delay--to assemble spatial sound pieces that were far removed from earlier compositions such as Saturn. Recordings and live performances often featured passages for unusual instrumental combinations, and passages of collective playing that incorporated free improvisation. It is often difficult to tell where compositions end and improvisations begin. In this era, Sun Ra began conducting using hand and body gestures. This system inspired cornetist Butch Morris, who later developed his own more highly refined way to conduct improvisers. Though often associated with avant-garde jazz, Sun Ra did not believe his work could be classified as "free music": "I have to make sure that every note, every nuance, is correct... If you want to call it that, spell it p-h-r-e, because ph is a definite article and re is the name of the sun. So I play phre music - music of the sun." Seeking to broaden his compositional possibilities, Sun Ra insisted all band members double on various percussion instruments - predating world music by drawing on various ethnic musical forms - and most saxophonists became multireedists, adding instruments such as flutes, oboes, or clarinets to their arsenals. In this era, Sun Ra was among the first of any musicians to make extensive and pioneering use of synthesizers and other various electronic keyboards; he was given a prototype Minimoog by its inventor, Robert Moog. According to the Bob Moog Foundation: "Sun Ra first met Robert Moog after Downbeat journalist and Sun Ra acquaintance Tam Fiofori arranged for a visit to Moog's factory in Trumansburg in the Fall of 1969....it was during this visit that Moog loaned Sun Ra a prototype Minimoog (Model B), several months before the commercial instrument (Model D) was introduced in March 1970. Ra immediately added the instrument to his repertoire of keyboards, later acquired a second, and featured the Minimoog prominently on many of his recordings of the early 1970s." Notable titles from this period include The Magic City, Cosmic Tones for Mental Therapy, When Sun Comes Out, The Heliocentric Worlds of Sun Ra, Volume One, Atlantis, Secrets of the Sun and Other Planes of There.
