There are essentially two different eras of Genesis. The first was led by Peter Gabriel, who would dress up like a flower onstage and sing 25-minute songs about lawnmowers. The second, fronted by drummer Phil Collins after Gabriel left for a solo career in the mid-'70s, was dominated by pop songs that made the group one of the most popular in the world. There have been various lineup shifts since the band's formation in England at the end of the '60s, but the core quintet of Gabriel, Collins, keyboardist Tony Banks, bassist Mike Rutherford and guitarist Steve Hackett (and then a trio of Collins, Banks and Rutherford) made most of the group's classic records. Collins quit in 1996, and since then, fans have been clamoring for a full-group reunion.
