Wireless Festival performers will not be allowed to swear or wear "offensive" clothing as strict new licensing laws are enforced on the London event for 2019.
Artists will also be stopped from playing "vulgar, obscene or banned songs" during sets, engaging in "indecent acts", making lewd gestures, actions or remarks as part of the clampdown.
Pressure has been put on the festival by The Friends of Finsbury Park group, which tried in vain to have the license revoked altogether. While this hasn't happened, the rules for next year are unarguably severe, and don't stop with those booked to play.
Ticket holders will be asked to refrain from donning revealing clothing or other items that could "offend the general public". Attendees will also find new sound restrictions and tighter monitoring in place during Sunday, which will now finish at 9.30PM, half an hour earlier than Saturday's curfew.
Around 37,000 attended the two-day gathering this year, with two people tragically dying after the event. Local Democracy Service reports suggest there were 67 complaints in the aftermath, ranging from anti-social behaviour and drug dealing to litter and damage to property.
Organisers also came under fire when 2018's initial line-up featured just three female performers, leading to the introduction of an all-women stage curated by Rinse FM. Bad Gyal, Lady Leshurr and Barely Legal were amongst those on the revised bill.
Earlier this month it was revealed another London festival, Field Day, will relocate for 2019 after an uneasy debut edition at Brockwell Park sparked concerns from local residents. Meanwhile, in the US, Ultra Music Festival Miami has been dealt another blow in its efforts to stay at Bayfront Park, the event's spiritual home since 1999. Complaints relating to anti-social behaviour, traffic and noise have all factored in the current decision not to agree a proposed contract extension for the site.
