Why this is not recognized as Pink Floyd's chef d'oeuvre is beyond me. There is more in the 45 minutes of this album to justify the Floyd's enshrinement in the pantheon of rock godhood than all of their subsequent output combined.
To begin with, there is "One of These Days." The doubled bass tracks (Echo-plexed and stereo-tracked to swirl from left-to-right and back) anticipate much electronic music -- witness ABBA, Morcheeba, Massive Attack, Moby, Oakenfold, Radiohead, Zoot Woman, etc.
"A Pillow of Winds" showcases the dreamy Hammond organ stylings of Rick Wright and the acoustic guitar part-writing of Dave Gilmour. If this track does not stand as tall as the rest of the album, it is only because it is an oak amongst redwoods.
"Fearless" is the first great demonstration of Roger Waters's obsession with insanity, self-regard, and schizophrenia, later to become de rigeur on "Animals," "The Wall", and "The Final Cut." Its creepiness is bolstered by the crawling octave figures in Dave Gilmour's guitar part, which seem to illustrate, in musical terms, the narrator's growing paranoia and dissociation from the world around him. "You'll never walk alone," indeed. Actually, you may walk alone over the cliff of madness, but at least your precipitation therefrom will be accompanied by a Gilmour guitar-figure.
"San Tropez" follows on insanity of "Fearless", and actually turns out to be its reiteration and intensification. The reprieve from Watersian dissociation is merely a hazy, cocktail-inflected hour of jazz.
"Seamus" diverts from the atmosphere of dreariness which has begun to take root. The stage is now clear for the quasi-symphonic titan which concludes this album.
The hydrophone pings which begin "Echoes" bely its outer-space origins -- the starting couplet of which originally went "Planets meeting face to face/Hang motionless upon the air." The opening, in a sort of Handelian French-overture dotted rhythm, eventually gives way to an extended funk-rock workout (with much bending and releasing from the ever-fertile Gilmour and chopping and draw-bar manipulation from the Hammond-frying Wright).
In all, "Echoes" moves strength to strength, proving itself to be the reason for buying "Meddle", pushing 70s progressive rock from the realm of curiosity (or straight classical paraphrase) to actual direct musical expression.
When you have finished the album, the feeling is one of accomplishment, or that of having flown over a large, wide-horizoned vista.
