Ambient music is not made for supporting an ambience, it's all about creating one, but isn't it the purpose of many musics ? Listen to Bitches Brew, the first Weather Report's albums, Pink Floyd's Middle among others - and what a name for a band, Weather Report, talking about musical climates ! Many people consider it has all started in Germany and not in America, at the beginning of the seventies, with musicians like Klaus Schulze and Tangerine Dream.
