One of the seminal progressive rock bands, Genesis began in the late-'60s as post-Beatles visionaries with a taste for orchestrated pop melodrama, but quickly mutated into purveyors of ambitious, classical-tinged art rock. After flamboyantly theatrical vocalist Peter Gabriel left (eventually followed by guitarist Steve Hackett), the group gradually turned toward more accessible material under the stewardship of singing drummer Phil Collins. By the '80s, Genesis had become an unstoppable hit-singles machine. Meanwhile, both Gabriel and Collins went on to lucrative solo careers. The band called it a day in 1997, shortly following Collins's departure, but reunited a decade later for a major world tour.
