The frontman for Soundgarden and Audioslave died suddenly last night, within hours of performing a sold-out concert.
Chris Cornell, who attended the March 25th L.A. event marking Elton's 70th birthday and the pianist's half century of writing with Bernie Taupin, was just 52.
Elton posted a photo of Chris on Instagram, along with the following:
''Shocked and saddened by the sudden death of Chris Cornell. Great singer, songwriter and the loveliest man. My condolences to his wife and family, bandmates and friends.''
Many others also reacted. Dave Navarro said it was ''a terrible and sad loss,'' leaving him ''so so stunned,'' while Nile Rodgers referred to him as ''my bro,'' and Perry Farrell said that a ''shining voice in music has left us in the midnight.''
Sebastian Bach wriote that he had tears in his eyes and Joe Perry spoke of the vocalist's ''great talent.''
Peter Frampton described him as being ''a brilliant artist on so many levels,'' and Jimmy Page said Chris was ''incredibly talented, incredibly young, incredibly missed.''
