Only four years separate the release of Guns N’ Roses’ first full-length record, 1987’s Appetite For Destruction, and Pearl Jam’s 1991 debut, Ten. But in the narrative of rock history, these albums represent signposts for completely different eras; 20 years ago, GN-effin’-R and Pearl Jam might as well have existed in different dimensions. Time, however, has a way of erasing such distinctions. Today, Appetite For Destruction and Ten reside in the same general vicinity of reassuringly familiar classic rock. That one comes dressed in coke-splattered scarves and the other in bong-saturated flannel has been obscured by the sands of time.
