French Progressive Rock
First, I want to thank groscochon for all the music he's been linking to. I'm making a nice playlist of music to cook to from all the songs he's been posting.
However, some people are also interested in progressive rock. The main names in progressive rock are English (Yes, Genesis, Emerson Lake & Palmer, Gentle Giant, etc.), but there were, and still are, progressive rock bands from France.
Last year an article was posted to ProgSphere listing the 20 Best French Prog Bands. In case you're interested, here's the list.
If you like progressive rock and know of other French bands, add them below in the comments. A quick review wouldn't hurt, either.
