The Soundgarden, Audioslave and Temple of the Dog frontman, who also ran a successful solo career, has died at the age of 52.
Cornell's last tweet came Wednesday night when the musician shared a photo of the venue the band was set to play at. His family is reportedly working with the medical examiner to determine the cause of death. "They would like to thank his fans for their continuous love and loyalty".
As the lead singer for Seattle-based Soundgarden, Cornell helped architect the 90′s grunge rock movement.
The band, who had released hit songs and found success, marked a mainstream breakthrough with "Superunknown", its 1994 album that won them two Grammys, sold more than five million units in the USA, and launched five hits, including "Black Hole Sun", one of the most popular alternative rock songs from the 1990s.
Formed in 1984 by Cornell, guitarist Kim Thayil and bassist Hiro Yamamoto, Soundgarden released their third studio album, Badmotorfinger, in 1991, featuring popular singles including Jesus Christ Pose, Rusty Cage and Outshined.More news: Springfield police remember fallen officers

In 2001, Cornell joined with three former members of Rage Against the Machine to form Audioslave. It included hit singles Spoonman, Fell on Black Days, Black Hole Sun, My Wave and The Day I Tried to Live.
Similarly, 1996's Number Two-charting Down on the Upside, contained several hits ("Pretty Noose", "Burden in My Hand", "Blow Up the Outside World", all written by Cornell) and a Cornell-written outtake from that album, "Bleed Together", featured on the band's A-Sides comp would be the group's final hit before their 1997 breakup.
Cornell became another in a line of lead singers from major grunge rock bands to pass away. He says Cornell's wife called a family friend and asked him to check on Cornell.
