6. Soundgarden, 'Superunknown'
Nirvana had fused punk and metal on Nevermind but no band wore its hesher, Zeppelin-loving integrity with as much as pride as Soundgarden. Having proven themselves masters of Seattle sludge, the band worked to expand their sound on Superunknown and came up with grunge that's aged as well as anything else from the era. "There is a degree of maturity at work," said guitarist Kim Thayll. "You can hear it in our decision not to rev the engine so high. In the end I think it's more powerful." Emphasizing fluid rhythm and sinewy dynamics as much as torpid, throbbing riffs, songs like "Black Hole Sun" and "Head Down" opened up new emotional possibilities for singer Chris Cornell who emerged as Nineties metal's greatest druid existentialist: "When the whole thing washes away don't run to me," he growls on "Limo Wreck." We wouldn't think of it! Jon Dolan
