A unique album in many ways, and it still sounds good after more than 50 years. Only a few long tracks (or should I call it symphonies) on the album. Ground-breaking synths with acoustic instruments too and all played by the same, young (23?) Mike Oldfield. Has elements of minimal classical music. Not a 5 for me because it's all a bit cold and academic and doesn't really move me. It's a bit too show-off like (try and cram as many instruments and variations in as possible). Still, quite a feat and a definite "must hear".
