Genesis were an English rock band formed at Charterhouse School, Godalming, Surrey, in 1967. The most successful and longest-lasting line-up consisted of keyboardist Tony Banks, bassist/guitarist Mike Rutherford and drummer/singer Phil Collins. Significant former members were original lead singer Peter Gabriel, and guitarists Anthony Phillips and Steve Hackett. The band moved from folk music to progressive rock in the 1970s, before moving towards pop at the end of the decade. They have sold 21.5 million copies of their albums in the United States, with worldwide sales of between 100 million and 150 million.
Formed by five Charterhouse pupils including Banks, Rutherford, Gabriel, and Phillips, Genesis were named by former pupil Jonathan King, who arranged for them to record several unsuccessful singles and their debut album From Genesis to Revelation in 1968. After splitting with King, the group began to tour professionally, signed with Charisma Records and recorded Trespass (1970) in the progressive rock style. Following the departure of Phillips, Genesis recruited Collins and Hackett and recorded Nursery Cryme (1971). Their live shows also began to be centred on Gabriel's theatrical costumes and performances. They were first successful in mainland Europe, before entering the UK charts with Foxtrot (1972). In 1973, they released Selling England by the Pound (1973), which featured their first UK top 30 single "I Know What I Like (In Your Wardrobe)". The concept album The Lamb LiesDown on Broadway followed in 1974, and was promoted with a transatlantic tour featuring an elaborate stage show. Following the Lamb tour, Gabriel left Genesis in August 1975 to begin a solo career.
