Alice In Chains put a darker spin on '80s hard rock, wielding a bubbling-tar grunge sound that anchored the '90s alternative movement. “Would?” is rattled by guttural guitars and a shuddering bassline, while the psychedelic taffy-pull of "Grind" churns like a cement mixer. Hypnotic harmonies, led by late vocalist Layne Staley, mesmerize like a snake charmer on the percussion-heavy "No Excuses" and the metallic detonation of "Them Bones." And the dirge-like "Rooster," a tribute to guitarist Jerry Cantrell's Vietnam veteran father, is a searing personal statement.
