i'm pretty much in agreement with what people have said here:
1) "Foxtrot" is a decent to great effort, with "Supper's Ready" one of their finer moments ~ or would that be finer 20-odd minutes? there are a few other good songs on there, but "Supper's Ready" is the shizz.
2) "Selling England By The Pound" might be my favorite record of theirs. it jams ("Dancing Out With the Moonlit Knight"), it's got great airy guitars by Steve Hackett throughout, it borders on fusion (the second half of "Cinema Show" with Phil Collins doing his best impersonation of Billy Cobham), it gets wordy and witty ("The Battle of Epping Forest") and you get a long, drawn-out keyboard thing on "Firth of Fifth." really good record.
3) "The Lamb Lies Down On Broadway" might be their best record. while the first disc is incredible, the second lags in a few parts. talk about wordy...and talk about attempting to decode a record ~ this would be the one to try and decode. i think i got as far as it's a journey...looking for one's identity. a lot of highlights on this record, including "In The Cage" and "Back In N.Y.C.," to name but two. you'll enjoy this one.
4) it took listening to the most recent remastered version of "Trick of the Tail" for me to fully enjoy it. GREAT stuff! it was also interesting to hear in the interview (i think) that "Squonk" was a bit influenced by Led Zeppelin's "Kashmir" ~ or at least the drum part of the song. one of my favorites. as well as "Dance On A Volcano" and a few others. Phil is really in his Brand X/jazz fusion days here, drumming the shit out of some of those songs ~ like "Robbery, Assault And Battery," which is an otherwise goofy song at best.
5) "Wind And Wuthering" ~ i remember listening to this on vinyl and thinking it was mediocre at best. the new remastered version sounds MUCH better. it's not everybody's cup of tea, but would be worth coming back to after you pick up the others. i love "Afterglow" ~ makes me think of my wife.
6) "And Then There Were Three" is probably the least of the records i'm going to mention. there are good parts. i used to love "Down And Out" (the opening track), but i don't know if it wears well after repeated listens. about half of the songs are good, but the other half are a little iffy.
7) "Duke" ~ i don't really understand why this one is so highly regarded ~ by fans and the band alike. i think Tony Banks stated that it was only on this record that he noticed Phil becoming a "real" singer. i like the "Duke suite" of songs (including "Behind The Lines," "Duchess," "Turn It On Again," "Duke's Travels" and "Duke's End" (and i think "Guide Vocal," which is kind of lame)), but not much of the rest of the record.
8) "Abacab" sometimes gets a bad rap. but it's good and, yes, probably the last place you should stop (unless you want to pick up "Three Sides Live" ~ the live version of the song "Abacab" is much better played live, as they have two drummers going). i like all the songs except that stupid "Whodunnit" crap. if they would have put "Paperlate" on this record, instead, it would have been a great(er?) record. but no, Ahmet Ertegun has to come in and say "put 'Whodunnit' on the record." like Ahmet Ertegun knows anything...
enjoy!
