The title of Th1rt3en points to the album's place in the Megadeth catalogue: the thirteenth studio album, originally released in 2011. It is the first record since The World Needs a Hero (2001) on which co-founder David Ellefson plays bass again. 'Sudden Death' was written for the game Guitar Hero: Warriors of Rock and 'Public Enemy No. 1' deals with gangster Al Capone. Several songs, among them 'New World Order' and 'Millennium of the Blind', had existed as demos for years and got their first official release here. This edition is a 2-LP.
