Festival Lineup Graspop 2015

Belgium's Graspop Metal Meeting has drawn thousands of headbanging pilgrims since 1996, and the fearless faithful were hit with a particularly killer lineup in 2015. This best-of-the-festival list boasts the alternative heavy blows of masked mosh-pit favourites Slipknot, rock party classics by Kiss, the ferocious funk of Faith No More and Within Temptation's symphonic siren call.
