DATA is the brainchild of Norwegian musician / songwriter / producer Georg Kajanus, who was mosty notably responsible for 70's band Sailor and for producing Peter Godwin's "Images Of Heaven" (excellent track!).
His band DATA fromed in 1980 consisting also of vocalist sisters Phil and Frankie Boulter and released their debut album in 1981 titled Opera Electronica. This is the title (& closing) track from that LP. Coming off something like Queen meets Kraftwerk meets Wendy Carlos, the track is an sweeping electro-classical ride and lots of fun... It was also featured as the music for an award winning short film titled "Towers Of Babel".
