Check out “Tresspass” by Genesis from 1970, as well, (Phil Collins had yet to join the band), but it’s still a great album (especially ‘The Knife’)
Genesis with Peter Gabriel was one of my all time favorite bands. I particularly liked “The Lamb Lies Down on Broadway” and “Selling England by the Pound.”
The first time I heard of Genesis was seeing them live in concert. They were the warm-up for Humble Pie (just after Framption left). I was stoned (my normal state at that time) and the lead singer came out on stage dressed in outrageous costumes with masks. That, alone, caught my attention, but the music was awesome.
