Since 1993, popular music magazines in the USA such as Rolling Stone have reported the outbreak of an alternative music ‘revolution’, as bands such as Green Day (who trace their musical roots to late-1970s punk groups such as the Sex Pistols) achieve large-scale popular success. In September 1994 the Boston Globe newspaper devoted significant coverage to the free Green Day concert in Boston that was cancelled midway through as the crowd of 70,000 (comprised mostly of teenagers) threatened to overwhelm the security guards. The news media have focused their attention on the dancing known as ‘slamdancing’, or ‘moshing’, which is associated with this newly popular music. Slamdancing and moshing are two different, albeit similar, styles of dance in which participants (mostly men) violently hurl their bodies at one another in a dance area called a ‘pit’. The media attention paid to this music and its associated violent audience-behaviour paint them as emerging threats to public safety. On 10 September 1994, the Globe reported that ‘there have been severe injuries in mosh pits, where fans act out the hostile lyrics of groups such as Green Day’.
