U2: Pop

U2 have a fine sense of event and how to tweak it. Preceded by advance publicity suggesting more than enough stylistic innovation to maintain the band's reputation for playing unsafe, a calling card single called 'Discotheque' and, worse still for die-hard fans who prefer their U2 on the monumental side, bearing the worryingly lightweight title Pop, the new U2 is 1997's first must-hear album.
