Pink Floyd's concert tour in support of their double concept album The Wall. Only 31 shows were performed across four venues: Los Angeles Sports Arena, Nassau Coliseum (Uniondale, NY), Earls Court (London), and Westfalenhalle (Dortmund). The elaborate production featured a massive wall built across the stage during the show, with projections, puppets, and pyrotechnics. The final show on 17 June 1981 was Pink Floyd's last concert with Roger Waters.
