Cornell was considered a cornerstone of Seattle's grunge rock movement which swept the nation in the early 1990s. But Soundgarden was founded much earlier in 1984 in Seattle by Cornell, guitarist Kim Thayil and bassist Hiro Yamamoto.

The Grammy award-winning band went on a 13-year hiatus between 1997 and 2010. For part of that time Cornell fronted the group Audioslave with members of Rage Against the Machine. He also released several solo albums.

Soundgarden was back in business, however, touring the U.S. once again. Cornell's sudden death leaves an uncertain future for the rock band.
