The event runs until Sunday evening at the Norfolk Showground and drum and bass band Rudimental will bring the festival to a close.
The Saturday headliner was rapper Bugzy Malone and other acts that have performed so far include Becky Hill, Joel Corry and Example.
At the event, there are four stages which are the main stage, The Castle, The Nest and Mystree and there is also a VIP area.

Revellers at the event were dressed in colourful costumes and the site was a sea of bucket hats.
Ticket-holders also enjoyed fun fair rides and food from a range of vendors, with a long queue at the McDonald's free chicken nuggets kiosk.

After the event was cancelled in 2020 due to the pandemic, it seemed everyone was happy to be back.
