A previously unheard Chris Cornell song has been released.

The late Soundgarden and Audioslave frontman's widow Vicky is carrying on her late husband's legacy by releasing songs on the new posthumous career-spanning album and box set, 'Chris Cornell', and she was able to unearth a gem in 'When Bad Does Good'.

The track was produced, recorded, and mixed by the 'Black Hole Sun' hitmaker - who took his own life last May aged just 52 - and was discovered in his personal recordings archive and, without a reminder from Chris' close friend, 'Deadpool 2' actor Josh Brolin, the song may never have seen the light of day.

Speaking about the forthcoming record and boxset, Vicky said: ''Since Chris' sudden passing I have put all my efforts and energy into sharing his music and legacy with his fans from all over the world.

''I felt we needed to create a special collection to represent all of him - the friend, husband and father, the risk taker and innovator, the poet and artist.

''His soaring vocals found their way into the hearts and souls of so many.

''His voice was his vision and his words were his peace.

''This album is for his fans.''

The track is one of 11 that have never been heard before.

Earlier this year, Chris' daughter Toni shared a duet of her singing Prince's 'Nothing Compares 2 U' - which also features on the album - with her late father to mark Father's Day.

The late rocker's 14-year-old girl shared a touching tribute to her dad by posting their cover of the late 'Purple Rain' hitmaker's song.

Toni - who has siblings Lillian, 18, and brother Christopher, 12 - also shared an emotional message, thanking the her parent for being ''the best father'', whilst admitting that she wishes she could relive the day they sang together ''100 times over''.

Alongside a clip of their haunting and beautiful cover, Toni wrote on Chris' Instagram: ''Daddy, I love you and miss you so much. You were the best father anyone could ask for. Our relationship was so special, and you were always there for me. You gave me courage when I didn't have any. You believed in me when I didn't. I miss your love every day. Recording this song with you was a special and amazing experience I wish I could repeat 100 times over and I know you would too. Happy Father's Day daddy, nothing compares to you. [sic]''

Vicky hosted a vigil to mark the one-year anniversary to his death on May 18 at Los Angeles' Hollywood Forever cemetery.

'Chris Cornell' is released on November 26 and is available to pre-order now.
