Est... Folle is the third album by experimental French singer Brigitte Fontaine, released in 1968 on the Saravah label. Fontaine herself considers this to be her first real album. Jean-Claude Vannier was responsible for the arrangements.
The album received a 7.3 rating from Pitchfork, which described it as "playful and charming, even if it offers few hints at the curveballs ahead." AllMusic gave it a four and a half rating.
PopMatters assigned it a score of eight out of ten, remarking "Here, on the albumâÂÂs final number, she just sounds enamoured by the whole process of simply singing."
