French psychedelic/prog/folk underground of the early to mid 1970's. Established as Maajun and later subtly changing name. As Mahjun they made two eponymous albums on Saravah and a third on Gratte-Ciel called "Happy French Band", all eccentric French prog underground with lots of folk and cultural references. After Mahjun split (in the late 1970s) Jean-Louis Lefebvre formed a new short-lived Mahjun before continuing as solo.
