A press release just arrived from Activision, announcing that a new DLC for Guitar Hero III: Legends of Rock is now available on Xbox LIVE Marketplace and will be hitting PSN Store later in the day.

The new content brings something for No Doubt fans in the form of three songs from the band’s Tragic Kingdom album. Those songs being “Excuse Me Mr.”, “Sunday Morning”, and of course the song the band became world famous for, “Don’t Speak”.
