Christopher John Cornell was an American singer, songwriter, and musician, best known as the lead vocalist and rhythm guitarist for the rock bands Soundgarden and Audioslave, and for his numerous solo works and soundtrack contributions. Cornell was also the founder and frontman of Temple of the Dog, a one-off tribute band dedicated to his late friend Andrew Wood.
Cornell is considered one of the chief architects of the 1990s grunge movement, and is well known for his extensive catalog as a songwriter, his nearly four-octave vocal range, and his powerful vocal belting technique. He released four solo studio albums, Euphoria Morning, Carry On, Scream, and Higher Truth; the live album Songbook; and two compilations, The Roads We Choose and Chris Cornell, the latter released posthumously. He received a Golden Globe Award nomination for his song "The Keeper", which appeared in the 2011 film Machine Gun Preacher, and co-wrote and performed "You Know My Name", the theme song to the 2006 James Bond film Casino Royale. His last solo release before his death was the charity single "The Promise", written for the ending credits for the 2016 film of the same name.
