expanding beyond punk rock, the ex have incorporated a wide array of influences, often from non-western and non-rock sources. some include hungarian and turkish folk songs, and more recently music from ethiopia, congo and eritrea (the independence song of eritrea is covered by the ex to kick off their 2004 album "turn"). other examples of branching out stylistically include the improvised double album "instant" and a release under the moniker "ex orkest", a 20 piece big band assembled for performances at holland festival.
