One of the best bands of recent decades, Genesis has delivered an impressive string of familiar chart hits. Formed in 1967 and known as a “prog-rock” or progressive rock band, Genesis didn’t crack the US charts until 1978, when they began writing and producing more hummable, radio-friendly material. We follow the band from its beginning, paying attention to the musicians who left as well as those who stayed. It seems unique that those who left seem to be on good terms with those who remained, even revisiting Genesis material in their own recordings.
