Me, I've been a long time Genesis fan. I found a tribute CD entitled "Supper's Ready--Another Serving From the Musical Box" (i think that's what it's called) so I decided to buy it. Not a bad CD, it had some good bands/artists like Annie Haslam (of Renaissance), World Trade (Yes's Billy Sherwood),....and this band I had never heard of called Enchant doing a cover of "Man of Our Times". I was blown away by their version; in fact I liked it so much I went to Amazon.com and ordered Juggling 9 or Dropping 10 right away. I've been a fan ever since.
I also got a Yes tribute CD with Enchant doing a version of "Changes" but this wasn't quite as impressive as Man of Our Times. (and yes, I only really bought it because it had Enchant on it).
