As the leader of Genesis in the early '70s, Peter Gabriel helped move progressive rock to new levels of theatricality. In his solo career, Gabriel was no less ambitious, but he was more subtle in his methods. With his first eponymous solo album in 1977, he began exploring darker, more cerebral territory, incorporating avant-garde, electronic, and worldbeat influences into his music. The record, as well as its two similarly titled successors, established Gabriel as a critically acclaimed cult artist, and with 1982's Security, he began to move into the mainstream; "Shock the Monkey" became his first Top 40 hit, paving the way for his multi-platinum breakthrough So in 1986.
