Devote enough time to sifting through Genesis' heady prog years, and you'll realize they were catchy from the get-go. The 1969 gem “In Limbo” is psych pop awash in hazy harmonies and horns; “Robbery, Assault and Battery” sports a melody that's as playful as a nursery rhyme. “After the Ordeal” is wispy folk rock that blossoms into a gorgeous dance between flute and sinewy guitar leads.
