Edgar Froese, electronic music pioneer and founder of the band Tangerine Dream, was on a lifelong mission to find the ultimate sound. A tribute to the musician, who died in 2015, and to the era of electronic music.

"Tangerine Dream is science fiction!" Electronic music pioneer Edgar Froese founded the band Tangerine Dream at the end of the 1960s. He was on a lifelong mission to find the ultimate sound. He used heartbeats and breathing sounds, and experimented with synthesizers and sounds recorded in space by NASA and ESA. He created worlds of sound that catapulted listeners into otherworldly spheres and expanded their consciousness. In the 70s and 80s, Tangerine Dream launched the "Berlin School", banned conventional instruments from the stage and replaced them with Moog synthesizers the size of an altar. Their spectacular performances enthralled hundreds of thousands of fans around the world. The band's supporters, fans and friends included Salvador Dalí, David Bowie, Richard Branson and famous Hollywood directors such as Ridley Scott, Michael Mann and Kathryn Bigelow, with whom Tangerine Dream produced numerous film scores. Previously unpublished, private film footage and interviews with close acquaintances, band members and fellow artists trace the unique story of Tangerine Dream: a tribute to the musician Edgar Froese, who died in 2015, and the era of electronic music.
