Query: From Genesis To Revelation

Having been a fan of Genesis from what I thought was the inception (Nursery Cryme) - well, at least in the formula that consecrated them - imagine my Revelation when I started to dig in their earlier work and found out about this guitar player, Anthony Plillips, which quit the band before it became famous. Digging a bit further I found he actually had a solo career. Listening to his albums, I then understood that much of what I loved about the early '70s sound of Genesis was based on his contribution. Not to diminish the roles of the other giant artists that comprised this most accomplished prog rock band, of course, but one needs to listen to this album and judge for themselves. The music is sublime and even if you don't agree on this point, it will be at least an interesting historical finding. A must have for any prog rock fan.
