Superunknown proves that a grunge record can endure without the romance of a dead singer. In some ways, the album bests In Utero, Nirvana’s last official mark on the world that came out just half a year earlier, at the end of 1993. It’s less raw, but more technical; less humorous, more tightly woven. Soundgarden never threw up their hands and tossed musicianship to the wind like Nirvana. Their songs were never about helplessness as much as they were about power.
