Wireless Festival will reportedly have to ask artists not to swear or wear “offensive” attire

For the past four years, Wireless Festival has set up camp at Finsbury Park in London. This year's lineup included Stormzy, Migos, Lil Uzi Vert, and a surprise appearance from Drake. But Friends of Finsbury Park, a nonprofit that oversees the park's happenings, was unhappy with the behavior of attendees following the festival's culmination in July, BBC reports.

Haringey Council still granted a license for the festival to be held at the park in 2019, but is imposing a strict set of guidelines going forward. They specifically ask that "performers do not sing or play any vulgar, obscene or banned songs or carry out indecent acts or make any vulgar gestures, actions or remarks during the performance."

The council also requests that performers avoid "offending the general public" by refraining from wearing "attire which expose the groin, private parts, buttock or female breast(s)." The 2019 Wireless Festival lineup has yet to be revealed, and though Live Nation has not yet commented on the new restrictions, a representative reportedly said that the company was committed to the "possibility of improving year-on-year" at a hearing earlier this month.
