News of his sudden passing sent shockwaves through the music industry as stars such as Elton John, Jimmy Paige, Nile Rodgers, and Gavin Rossadale paid tribute to the grunge artist. According to his representative.

Cornell began his career in the Seattle rock scene. He was 52. Soundgarden was the scheduled headliner for Pointfest on Saturday in Maryland Heights, Missouri. We are all getting up to head out to our show at Rock On The Range tomorrow where they were set to headline. A full autopsy report has not yet been completed. The Detroit News cited Freeman in a similar report. A police spokesman told two Detroit newspapers that the singer was found with a band around his neck. The death has been ruled as a suicide.

A statement later posted on Facebook by the Wayne County Medical Examiner's Office stated that the "cause of death has been determined as suicide by hanging". "The body was transferred to the medical examiner's office." . In a Mother's Day message on Twitter, he called her the "perfect mother and the flawless wife".

This particular song may not be the first song of the singer's that we think of (I'd argue that honor goes to "Black Hole Sun" or "Spoonman"), but it absolutely carries the signature of Cornell: rocking, rollicking, and bursting with energy.

A concertgoer tells PEOPLE that Cornell was enthusiastic and energetic during his sound-out final performance Wednesday night.

"At 12 am (local time), we received a 911 call from the MGM Grand Casino Hotel".

A bench near the center of the sculpture was covered with flower arrangements, one of which included a note, "Say "hello" to Heaven", a reference to a song written by Cornell for a musician friend who died decades ago. After forcing open the hotel room door, Woody said the friend found Cornell on the bathroom floor. The band tweeted Wednesday night a quote from Cornell: "What I look forward to the the camaraderie".
