No. The album before, Bookends, is arguably better, but less
commercial - there's nothing as poppy as Keep The Customer Satisfied.
The other three albums are much less solid. Wednesday Morning, 3AM is
dreary whitebread folk (versions of Go Tell It On The Mountain and so
on, done very earnestly), Sounds Of Silence is a very good but not
truly great folk-rock album - not a bad song on it, but a few not-good
ones, and Parsley, Sage, Rosemary & Thyme is VERY patchy - a couple of
their best tracks, but a lot of filler that's either dated satire (A
Simple Desultory Philippic) or just overly-pretentious writing by
someone whose life experiences didn't match his ambitions as a writer
(The Dangling Conversation).
My advice - you NEED Bookends, you could probably do with Sounds Of
Silence, forget the other two albums (since you have a greatest hits
anyway which will collect the few decent tracks from them) and also
get hold of The Concert In Central Park, if only to hear Simon's
better solo stuff interpreted by S&G.
