Franck Dervieux was born in France, and later moved to Québec. 'Dimension 'M'' is one of the earliest prog albums from Québec (1971). The root system for later bands such as Contraction and Ville Emard Blues Band. Keyboard heavy progressive rock, with a looser structure, making it highly appealing on repeated listens. A very important album, and one of Québec's finest.
