Genesis is a fascinating band, one of the few to fundamentally change musical styles (and singers) over decades while continuing to grow its audience.
They started as a folk rock band fronted by Peter Gabriel, then shifted to prog rock after Phil Collins joined as drummer and background vocalist. When Gabriel left the band in 1978 and Collins took over as lead singer, they started a gradual shift toward pop. That’s where they would ultimately find the most success, reaching their commercial pinnacle with 1986’s excellent Invisible Touch.
