Definitely a transitional album, and sort of an awkward leap between eras. Tony and Mike dominate (as they also would on CAS) since Phil is not quite ready yet to be a full contributor to the writing.
"Follow You Follow Me" was the first song Genesis song I ever heard, but in retrospect I think the full ATTWT album would not have been a good introduction to the band for me.
I think it says something about the album that only one of its songs (FYFM) ever made it into the band's long-term concert repertoire.
Definite high points for me are "Say It's Alright Joe" (a seemingly very underappreciated song), "Deep in the Motherlode," "Many Too Many" and "Undertow."
Thoughts on other songs:
"Ballad of Big" - Brought down by some rather poor lyrics (which have grammar problems on top of everything else, such as pointlessly switching between past and present tense).
"Snowbound" - Lovely tune but the lyrics are odd in an unappealing way. There was probably no good way to write a song about the apparent subject matter at hand.
"Burning Rope" - Not a bad song but too many lines of the lyrics make no particular sense.
"Scenes from a Night's Dream" - I like this song OK, but in order to appreciate it one really has to be familiar with the source material ("Little Nemo in Slumberland," a groundbreaking early 20th-century Sunday comic).
"The Lady Lies" - Starts out a little awkwardly ("come to lurehimtothedemon'slair") but it gets better. To me this seems to work better as a metaphor for something than as an actual story.
