Napalm Death became the first-ever grind band to play the U.K.'s Glastonbury Festival, and did so extremely well on June 22. Given the fact that Napalm Death is literally the band to have invented grindcore, who better to represent the genre?
Oh, and I think it goes without saying that the band completely crushed it. Though we'll see it anyway – Napalm Death is fucking good live.
