On their fourth album BGM, originally released in 1981, YMO continued where they left off with X∞ Multiplies, by venturing further into synthesizers, drum computers and experimentation with rhythm, sequences and speeds.

This album is more focused on atmosphere and mood. Some even say this album is a turning point for YMO and the international pop music scene. They successfully merged lyrics, sound bites and their signature electrically programmed music on BGM. “1000 Knives” and “Cue” are the most famous; ‘The Hand Clap’ on “1000 Knives” is probably one of the most used samples in the ‘80s, early ‘90s.

BGM is available on black vinyl and includes a 4-page booklet.
