Ayn Sulthor

Here are some :

Telephone (my favourite is "ça c'est vraiment toi")

Superbus (Lola, Butterfly)

Louise Attaque (j'temmène au vent)

Indochine (j'ai demandé à la Lune)

Noir désir (le vent nous portera)

Trust (Antisocial -> very fun to play on RS)

BB Brunes (Dis moi)

Jhonny Hallyday (as the song in last RSCS, is the most famous rocker for us, but its gentle rock, very mediatic. In France Rock is lacking a lot of presence on radios... Its a niche music style, and even more for metal, punk and all the "dark" variations.)

Ultravomit (one of my favorite metal band, parodic metal, but you have to understand french to get all the jokes ^^)

Gojira (the most famous metal french band, but sing in english, very cerebral)

I'm not used to blues music, so I can't really tell you good songs... 

Hope this will fill your knowledge a bit

A bientôt !

dwnld'd a couple songs and currently watching Ultra Vomit concert 2019. Awesome heavy metal play, which you are correct, need to understand French.
