From the 1976 album *A Trick of the Tail*, the first to feature drummer Phil Collins on vocals after the departure of Peter Gabriel. They searched for a replacement singer and couldn't find one they were happy with. Collins sang "Squonk" as a placeholder, but they were so happy with his performance that they decided to keep him on as lead singer and have him record the rest of the tracks on the new album, and he went on to be their full-time frontman. They brought in Bill Bruford and later Chester Thompson to serve as a second drummer on tour. In my opinion, this is prime Genesis material; it marks a shift into more radio-friendly material than the Peter Gabriel era, while still retaining their prog-rock roots. The success of Collins' 1981 solo album *Face Value* brought a change in Genesis' output to be much more pop-oriented. While 80s Genesis has some gems, mid- to late-70s Genesis is the perfect blend of serious musicianship and accessibility to everyday listeners.
