Not normally associated with the musical style of a Bond theme, Cornell was keen to record a track that was respectful to the Bond tradition.
Cornell was chosen partly as the producers wanted a strong male vocalist to reflect the grittier, inexperienced Bond (no male vocalist had sung a Bond theme since Morton Harket performed The Living Daylights in 1987). To record the title track, producers Michael G Wilson and Barbara Broccoli announced in July 2006 that former Audioslave and Soundgarden vocalist Chris Cornell would provide the theme for Casino Royale.
