A Trick of the Tail is the best Genesis album, and I’m a fan of the Gabriel-era (especially ‘The Lamb’). Every song on Trick is fantastic.
The problem was when Tony and Mike started letting Phil write.
BTW, if you haven't already, check out the YouTube videos of Steve Hackett's current project. Genesis Revisited is what he calls it, or at least what he called one of the tours. He has a singer that resembles Robert Plant with long, wavy blonde hair that would give a young Peter Gabriel a run for his money vocally. Nick Beggs - of Kajagoogoo fame, since this thread is 80's-related - plays bass.
