There are so many great song in my mother tongue that virtually nobody aside from the relatively few speakers could realistically even come into contact with. I’m certain all of you non-English speakers here can relate! I linked one of my favourite songs, what are yours?
French-Canadian here! If you like prog rock, you should check out Harmonium! I recommend their album “Si on avait besoin d’une cinquième saison”, here’s my favourite song of theirs.
Another classic is Beau Dommage, a folk rock group (with a bit of prog influence). Song recommendation: Le Géant Beaupré
To plug a more contemporary artist, P’tit Belliveau is an Acadian artist from Nova Scotia who does stuff influenced by traditional Acadian folk but with a lot of modern pop and electronic sound. I absolutely love everything he puts out, but check out RRSP/Grosse Pièce. His music videos are always stellar as well.
