They are one of the only French BM bands I really know of.
France has one of the strongest BM scences, starting with the whole LLN circle (Vlad Tepes, Belketre, Torgeist, Mütiilation, etc) who plays most of the time very raw and unpolished Black Metal.
If you like this stuff check out Zèpülkr, it's in the LLN tradition but a bit more polished.
Then there is Antaeus who play a very brutal form of BM. A newer band is Sordide, raw in style but brutal in sound. Or is Diapsiquir who are just pure chaos and one of the most unique BM bands ever.
Krüel Kommando, Mortifera, Sale Freux, Christicide, Sühnopfer, Arkhon Infaustus, Hell Militia, Glorior Belli who have transcended into Pantera-esque/Stoner Rock Black Metal or Nuit Noire (only songs about fairies) are all worth checking out and all play a different style of BM.
And of course there is Deathspell Omega. They started with more traditional Black Metal but have to became to blow up all boundaries and genre limitations. "Si Monvmentvm Reqvires, Circvmspice" is basically a must-listen for BM fans. And their split with Satanic Warmaster is one of the best splits ever (got a repress a few years ago so it's available again).
For NSBM fans or fans of "controversial" BM you have Kristallnacht, Autarcie, Necropole/Caverne, Elitism, Order of the Death's Head, Malsaint, Gestapo 666, Chemin de Haine and Osculum Infame.
Last but not least Peste Noire. Defenitely check out Peste Noire. Start with their first album and listen to all albums in the order they were released. It's one wild ride.
