"His birthday seemed the perfect time to share this and celebrate Chris, his voice, music, stories and art," said the estate on Cornell's Facebook page.
"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."
Happy birthday, Chris.
