It’s almost unheard of to read anything about GAS, Wolfgang Voigt’s ambient techno alias, without hearing that the project was created "to bring the forest to the disco, or vice-versa." While his records - all of which except this year’s Narkopop, were released nearly two decades ago - have always been evocative of the German woodlands in which Voigt spent his adolescence, his live performances go beyond, transporting their audience to a land of eery wonder with an assault of audiovisual beauty.
