Concert promoter Live Nation is pulling out of Hyde Park after more than a decade of putting on events there. The live music company, which has hosted a raft of concerts and festivals including Hard Rock Calling, Wireless and the Bruce Springsteen concert this summer, has cited issues including noise restrictions and curfews for the decision, The Guardian reports. The company has reportedly written a formal letter of complaint to the Royal Parks Agency over the tender process for the new five-year contract for the central London site, dubbing it "flawed". According to the Guardian, the letter raises issues such as noise, crowd safety considerations and unrealistic revenue assumptions. It is thought to be highly critical of the tender document, arguing that it doesn't take into account the complicated logistics of running big events in a central London location. The Hyde Park location has come under fire this summer after Bruce Springsteen and Paul McCartney's duet in July was switched off due to curfew issues, while Blur fans were left disappointed after noise restrictions meant many fans couldn't hear their Olympic reunion gigs. Live Nation has been putting on gigs in Hyde Park for over a decade.
