All this happens in June in Clisson, a working-class city in the Loire-Atlantique region of France. It is the muddy and metallic meeting point for disciples of hard rock and fans of the "big sound". Hellfest brings together some of the most important heavy-death-glam-black metal bands in the galaxy, and nearly 400,000 furious men and women in a trance. Good humor, taunts, dust and decibels on the program. Hell has never been so appetizing.
