This is not the 'official' psychedelic sound, but rather a sound that has been overlooked by revivals from the '60s to the '80s, ignored for lacking easy categorization. In 1970s France, moody orchestrations by Jean-Claude Vannier for the epochal Melody Nelson session with Serge Gainsbourg (as well as the less-acknowledged but artistically equal Brigitte Fontaine Est...) combined with the clash of exotic folk and cosmic jazz on the Saravah label to create an atmospheric and far-reaching sound that embraced open-mindedness, come-down grooviness, and the pristine (but definitely not smooth) production techniques of the time. It is a sound that's a purple haze without being “Purple Haze”, if you get my drift. Paris' Dirty Sound System have defined an amorphous genre, a rare thing in the compilations market, and have done it with a flow that betrays some serious mixtape obsession. A creepy and ominous mood is created by soundtrack greats François de Roubaix and Karl Heinz Schäfer, plus freaky pioneers Brigitte Fontaine and Dashiell Hedayat, along with many more.
