The present thesis discusses various aspects of the Irish rock band U2. Apart from providing an outline of important political, religious, and cultural backgrounds to the band?s development from the beginnings up to the year 1995, special emphasis is placed on the detailed analysis of four representative songs, ?Sunday, Bloody Sunday?, ?Bullet The Blue Sky?, ?Mothers Of The Disappeared?, and ?Miss Sarajevo?. The skilfully constructed lyrics, which make ample use of rhetorical and other poetic devices to enhance and underline the effect of the various arguments quite often, have a powerful effect on the listener. Of course, since songs are intermedial texts, the words interact with the music to create the overall effect and to make them more effective in terms of the usually political message underlying and motivating U2?s work. For instance, ?Sunday, Bloody Sunday?, U2?s most successful song, uses many powerful images, as well as shifting perspectives and focalization to engage, indeed captivate the listener's attention. Furthermore, figures of repetition are frequently used in the analysed songs to underline their various concerns and to give special emphasis to them. In performance another dimension of the songs is added. In Ireland, for instance, Bono tore apart the Irish flag, in order to be left with the white part, as a sign for peace. With these symbolic acts U2 is directly speaking to the audience and they are expressing their concerns, which are also briefly discussed in this thesis.
