Extreme metal emerged in the second half of the 1980s through three distinct musical genres with different principles, aesthetics and evolutions: grind core, death-metal and black-metal. Like all underground cultures, extreme metal is not a story which can be lived by proxy. And so it appears that some artists, whose works have been deeply affected by this, have actively participated in this scene since an age at which they probably didn't know that their thoughts would become works of art.
The Altars of Madness exhibition project displays and brings together the works of art of this generation of artists who were affected by extreme metal, accompanied by a few others who are pertinent witnesses of this musical scene or who have brilliantly contributed to shaping its iconography.
