In the fall of 71' in less than a 4 week period, I saw the supporting tours for not only Who's Next but also the albums Tarkus and Aqualung. And a Tull roadie was sporting what I thought was a religious T shirt but we smoked a joint and he turned me onto a band by the name of Genesis of which I became a huge fan of. But after Gabriel and Hackett left, so did I.
This and Trilogy are fantastic albums!
