Heavy rock began to fade after the 90s, but the angst of grunge never went away: it sublimated into new musical forms that dialed down the guitar amps, not the intensity. “The Calendar Hung Itself” and “Girl Anachronism” spill torrents of words like self-hating Livejournals, while “Atlantis To Interzone” and “Sparrow” are overtaken by alarms and cellular interference. Only Björk seems to find any catharsis in an overconnected world, until she begins to contemplate suicide as “Hyperballad”’s hammering house beat drops.
