Best Genesis Album - your opinions please.

Cuke's right - Seconds Out is great album - it has something for both factions. It's a live set from concerts shortly after Gabriel left the band. It includes a monster liver version of Supper's Ready and other great PG erra songs - with Phil Collins on vocals. It also has a few cuts off od Trick of the Tail.
I saw them in concert during this tour and the album does it justice.

Nursery Cryme is my favorite from the early years. The Definitive Edition Remaster sounds close to the vinyl from the 70's. On topic FYI: Genesis re-recorded "The Carpet Crawlers" in 1999 for their box set. Peter and Phil share the vocals. Worth a listen.

Selling England by Pound, an incredible piece of work, some of the best flute solo guitar work I have ever heared , very melodic, great work by steve hacket , remindes me of andy lattimer of camel. The other two are trespass and nursery cryme.

Forgot to mention that I am listening to selling england by pound almost everynight just before I go to bed...

I'm not surprised that Selling England BTP seems to be high on most peoples list, it's a sublime work that seems to capture the very best of the band. It's rare to find a recording where each track is of the highest standard, and I think that is where the Lamb falls down, there are some exceptional pieces but just too much mediocrity in between.
Genesis and Pink Floyd were my favorite bands through the late 70's and 80's, and it pained me each time Genesis released a new recording, to see the change in direction, and their promoting Collins as the main contributor. I disliked much of PC's whining about his marital problems through Face Value, and when he brought that into Genesis, it spelled the end of an era for me.
