The track, Autobahn, is a sublime, seminal, exciting, interesting, fascinating and above all, excellent piece of work. This music sounds great now - imagine what it must have sounded like in 1974! You're in your bedsit, monging out to Yes when yer mate comes round and puts this on the turntable; it must have been a tremendous experience. It's a little symphony of superb sonics, a coherent opus that can blow you away with its amazing noises and fantastic weirdness, excellent rhythmic progression and, let's say it again, great noises. Side two is a departure, but has some interesting stuff on it. But it's Autobahn itself which is the golden treasure. This should be studied by students of music. Maybe it is. If you like this, you'll also like Kraftwerk's TEE, also ace.
