I only saw Genesis once, in 1978, the tail end of their run as a prog band and a time when their live show was probably at its most polished, with plenty of the 'old' tunes still being played. It was my first big concert, and I remember enjoying it thoroughly. I went and bought ATTWT shortly after that, and it became a solid part of my fledgling record collection. The funny thing is that even then I thought it didn't have much in common with my other Genesis albums (Trespass, Nursery Cryme & Live), and more with two albums that were making an impression with me then: Boston's Don't Look Back and Thin Lizzy's Black Rose.
I've been listening to ATTWT on YT, and I find it can still move me even though it leaves me with the same dubious aftertaste, as it were, as Don't Look Back does. Ultimately I find it unfulfilling because it's rather two-dimensional in a way, as if the Band's horizons (no pun intended) had started to shrink (and dog, did they ever).
(Black Rose, now that's another matter—total masterpiece in its genre...)
Highlights for me are Deep in the Motherlode and Burning Rope.
