Top two personalities in prog

Tarkus was the first full-blown Prog album which I remember playing constantly at home when I was very young, it was the first Prog album which really blew my child mind off, with Keith's Hammond and Moog antics being like nothing I had heard before (mostly The Beatles, Stones, early The Who etc) leaving a long-lasting impression in me.

A bit later came Genesis from which Foxtrot was another of the top players at home, especially Supper's Ready which would play as if the "repeat" button of modern audio players already existed back then. All the music was astounding but for some reason it was Gabriel's singing which I found so special. We would all shout out loud to "A Flower?" in the transition between How Do I Dare Be So Beautiful and Willow Farm, it was so comical and we all laughed when shouting it, and Gabriel's theatrical way of singing all over the suite was also like nothing I had heard before (even if I barely knew two words in English at the time).
