This first YMO album was released in 1978 in Japan ('79 in Europe) and set a precedent in the music industry like never before. By releasing this daring album, YMO shook the world with their Synthpop','at the time a revelation as well as a revolution.

YMO created their own sound, far ahead of its time. The band was amongst the first to use a "computer music composer", which was a programmed Roland MC-8 Microcomposer developed by Hideki Matsutake (composer, arranger and computer programmer). The trio mainly used electronic equipment on this album. The only acoustic instruments used were a piano and marimba percussion set. This type of production was never heard of before and set about a new movement within the music business.

Featuring the hit "Firecracker", an infectious and exotic Martin Denny cover, which became a staple in the early Hip Hop scene in New York.
