The late grunge icon Chris Cornell would have turned fifty-six today. In honor of his birthday, his widow and estate have shared a previously unreleased cover of another rock classic, Guns N’ Roses‘ “Patience.”

“Patience” was originally released on Guns N’ Roses’ 1988 album G N’ R Lies as part of a set of acoustic songs. The song reached #4 on the US Billboard Hot 100 and became a staple of the band’s live performances. Cornell’s cover was originally recorded in Los Angeles in March 2016, while the artist was teaching his daughter Toni how to play the song. “Patience” was produced by Brendan O’Brien, with whom Cornell was working on a solo album of acoustic covers shortly before his death.

A statement on the artist’s Facebook account reads:

“His birthday seemed the perfect time to share this and celebrate Chris, his voice, music, stories and art. It is true a man is not dead while his name is still spoken…and, through his art, an artist’s soul still burns just as bright as ever upon all those that look up to him and his memory. Releasing music that was special to Chris keeps a part of him here with us- his heart and his soul. His love and his legacy.”
