This is Yellow Magic Orchestra's 2nd and probably most famous album. The first vinyl version came out in 1979, and YMO was awarded the annual grand prize for the best album of the year in Japan (1979) when the rest of the world didn't know much about computer electric pop music, something YMO called 'Techno Pop'. Germany's Kraft Werk was one of only a few other groups of this kind.
This album contains famous pieces, including 'Technopolis', which starts with a computerised voice saying 'TOKIO', written by Ryuichi SAKAMOTO ('The Last Emperor', 'Merry Christmas Mr Lawrence'); 'Absolute Ego Dance' (by Harry HOSONO); and probably the most famous YMO number 'Rydeen' (by Yukihiro TAKAHASHI). I personally love the YMO version of the Beatles 'Day Tripper' and the main theme 'Solid State Survivor (SSS)', in which the guitarist of Sheena & the Rokkets, Makoto AYUKAWA, takes part. By the way, SSS contains some strange electric 'coughs' and 'laughter', and a Japanese expression 'Moshi Moshi? (Hello Hello?)' can also be heard a few times. 'Rydeen' contains some 'horse running' noises too. The sound of synthesizers (especially 'Prophet 5'), synthe-drums and the futuristic melody are all amazing! But the most amazing thing is that this album was released in 1979! YMO came to London in 1979, even before they became famous in their home country of Japan.
FYI: YMO was re-united for one night only for the Live Earth event from Kyoto, Japan (07/07/07). They were the last group to appear on stage in Japan and played the legendary 'Rydeen' with a new interpretation, which you can see on YouTube.
