Reissue of the album published in 2015 by the Catalan pop-rock band Els Catarres. "Big Bang" maintained the atmosphere of its predecessor "Postals" (Halley Records, 2013) but with a more band sound. It includes twelve songs, many of them with astronomical references. The album's title comes from the first single, 'En peu de guerra' ('Up in arms'), an explosive song, wanting to party.
