I'm not a big Genesis fan (Peter Gabriel / Phil Collins or not)--this track is more complex and interesting than what I know of their "big hits." To my untrained ear, the layers are quite effective; it's a good song, pretty decent proto Brit Pop--definitely "a good song," but not very progressive. For me, "prog" means something more adventurous than Genesis (including Gabriel).

From about the same period (late 70's-early 80's) , this is my ideal of progressive British music: https://youtu.be/6-6ErlitcUQ
