The festival will for the first time be held in Manchester as well as London’s Clapham Common where it has been held previously.
Mischief MD Mitchell Kaye said: ‘Ben & Jerry's Sundae on the Common is a staple part of the festival line up, and we will promote both the London and Manchester events through social media, traditional media and generally by making mischief.’
Mischief’s remit is to manage all aspects of the event’s logistics along with the comms for the events being held on 23 and 24 July.
Mischief is currently Ben & Jerry’s retained PR agency in the UK.
Band line-ups are yet to be announced, but previous musical talents gracing the Ben & Jerry’s stage have included Florence & The Machine, Scouting For Girls, Marina and the Diamonds and Doves.
The bands will play London’s Clapham Common on one day, and Manchester’s Heaton Park on the other.
