Genesis began working on their concept album ,“The Lamb Lies Down on Broadway,” in the early 70,s and released it in 1975. It would be the last Genesis album with Peter Gabriel at the front mike. Figuring out what the title and the story-line are about has puzzled more than one critic. It’s almost like West Side Story on steroids. The album, released by ATCO Records, is no more than $25.00 but the single (commercial or promo copy) can get you $750.00 today.
