Pierre Barouh's label, most sessions produced by Daniel Vallancien (studios also hosted recording sessions for BYG, probably others). I bet brownie could chime in with more info.
I've got some of the easier-to-find Saravah LPs - Fontaine, Steve Lacy, Cohelmec, Jacques Higelin, plus the Trio Camera reissue. Lots of nice stuff, ranging from freaky French folk to free jazz. Have yet to score the J-C Capon LP on the label, or the Nana Vasconcelos solo.
Akendengue is from Gabon; gorgeous, folky Afro-pop.
