Festival Republic has partnered with Isle of Wight Festival promoter John Giddings’ Solo Music Agency to launch new open-air live event Dog Day Afternoon, which they claim will be the biggest punk celebration in London this year.

Dog Day Afternoon is scheduled to take place at Crystal Palace Park on 1 July with a line up including Iggy Pop, Blondie, Buzzcocks, Lambrini Girls and punk rock supergroup Generation Sex (Billy Idol, Steve Jones, Tony James, Paul Cook).

The show was announced at a launch event at the 100 Club on London’s Oxford Street which saw Absolute Radio’s Claire Sturgess host a panel discussion featuring Giddings, Blondie’s Clem Burke, Sex Pistols’ Glen Matlock, Generation X / Generation Sex’s Tony James and Buzzcocks’ Steve Diggle.

Dog Day Afternoon will see Generation Sex make their first UK appearance. Live Nation said the band will play a set of punk classics from both the Sex Pistols’ and Generation X’s extensive catalogues.
