I made a seach on the forum but it seems nobody mentionned it.

It's a music festival in Saint-Julien-en-Genevois, with some good stuff

-ZZ top

-Gotthard (with their new singer)

-John Paul Jones

-G3 (Joe Satriani-Steve Vai-Steve Morse)

and some others I don't know....

Have a look there http://www.guitare-en-scene.com/ for the program, the prices and the place.
