Kinda funny to see the occasional blanket statement in regards to people's enjoyment or awareness of prog. rock and whatnot ("I only like one album in the genre" "its all pretentious and boring, etc."). Progressive rock is an exceptionally vast "scene", with hundreds upon hundreds of releases from innumerable bands over the last four decades. People seem to look back on the 70's specifically when they think of the genre, but in reality there's plenty of great modern releases that might appeal to you even if you think all of it is overwrought.
None of you would like it if I wrote off your favorite Indie bands, Emo groups, hardcore bands, etc. via blanket judgements and the like. What makes you think such is acceptable in regards to progressive rock?
All this being said,
SEBTP may be quintessential for your typical proghead as far as
Genesis go, but I consider it overrated and even a tad weak in comparison to
Trespass or
Foxtrot. And this is coming from a guy who enjoys a great deal of their 80's output too.
