At the height of Nirvana’s success in the early ‘90s, Kurt Cobain slammed fellow Seattle grunge gods Pearl Jam in the press, labeling them bandwagon-jumping “corporate puppets” who aped his band’s style in the vapid pursuit of fame. Eddie Vedder, a great admirer of Kurt’s, never retaliated publicly, but their relationship grew strained as Pearl Jam’s popularity eclipsed Nirvana’s. Before the two could settle their differences, Cobain took his own life — leaving Eddie to simultaneously mourn the loss of his hero and make sense of their complex, adversarial bond.
