Joni Mitchell, CC (born Roberta Joan Anderson; November 7, 1943) is a Canadian musician, singer songwriter, and painter. Mitchell began singing in small nightclubs in Saskatchewan and Western Canada and then busking in the streets and dives of Toronto. In 1965 she moved to the United States and, touring constantly, began to be recognized when her original songs ("Urge for Going," "Chelsea Morning," "Both Sides, Now," "The Circle Game") were covered by notable folk singers, allowing her to sign with Reprise Records and record her own debut album in 1968. Settling in Southern California, Mitchell and her popular songs like "Big Yellow Taxi" and "Woodstock" helped define an era and a generation. Her more starkly personal 1971 recording Blue has been called one of the best albums ever made. Musically restless, Mitchell switched labels and began moving toward jazz rhythms by way of lush pop textures on 1974's Court and Spark, her best-selling LP, featuring her radio hits "Help Me" and "Free Man in Paris."

Philip David Charles "Phil" Collins, LVO (born 30 January 1951) is an English singer-songwriter, drummer, pianist and actor best known as a drummer and vocalist for British progressive rock group Genesis and as a solo artist.

Collins sang the lead vocals on several chart hits in the United Kingdom and the United States between 1975 and 2010, either as a solo artist or with Genesis. His singles, sometimes dealing with lost love, ranged from the drum-heavy "In the Air Tonight", dance pop of "Sussudio", piano-driven "Against All Odds", to the political statements of "Another Day in Paradise".

Collins's professional music career began as a drummer, originally in a band called The Real Thing with Andrea Bertorelli, who later became his first wife. Collins played drums and shared lead vocals (with Brian Chatton) in Flaming Youth which recorded one album, (Ark II). In 1970, he took over drums for Genesis, which had already recorded two albums. In Genesis, Collins originally supplied backing vocals for front man Peter Gabriel, singing lead on only two songs: "For Absent Friends" from 1971's Nursery Cryme album and "More Fool Me" from Selling England by the Pound, which was released in 1973. Following Gabriel's departure in 1975, Collins became the group's lead singer.
