He was born in Saint-Raymond. His father was a horse dealer.[3] Luc Plamondon began his studies in the arts at a very young age. He learned the piano and undertook classical studies at the Petit Séminaire de Québec. He says that he entered the seminary to be a priest and that he came out a poet.
However, when his interview was published, the word "poet" became "painter", hence the legend came up according to which he was introduced as an expert in painting. On the other hand, although he has never painted, he is a fan of modern painting.[4]
From 1976, he wrote, in collaboration with the composer Michel Berger, the rock opera Starmania, including SOS of an earthling in distress and A boy not like the others (Ziggy). Michel Berger chose him as lyricist precisely because he makes French sound in a particular way. The ambitious musical project, presented as the first French-speaking rock opera, was released on disc in the fall of 1978 with the help of French artists (France Gall, Daniel Balavoine), and Quebecois (Diane Dufresne, Fabienne Thibeault, Claude Dubois).[5]
