Dos (own spelling ¡Dos! ) is the tenth studio album by US punk band Green Day. It was released on November 9, 2012 by Reprise Records. Dos is the second album in a trilogy completed by the albums Uno (21 September 2012) and Tré (11 December 2012, or 7 December in Germany).
While Uno follows the punk rock sound of the early Green Day albums, the Dos songs are more oriented towards the rougher garage rock. Dos is stylistically strongly influenced by Green Day's side project Foxboro Hot Tubs (whose style can also be classified as garage rock); the song Fuck Time was first performed at Foxboro Hot Tubs concerts.
