The festival was last held in London in 2012
The event began in 2007 and ran until 2012 before going on hiatus. It will hold its first edition in four years at Three Mill Islands in Bow, East London on September 3.
In a press release, organisers promised the return of the festival would include a “pit party” new bands stage, where groups will play in the middle of the floor with audiences surrounding them. There will also be secret sessions and surprise guests across the day.
Limited early bird tickets will go on sale on Friday May 13 at 9am and will cost £24.95. For more info on tickets, click here.
Festival partner Rob Hallett said in a statement: “We’re excited to be working with Sean Mclusky on bringing back the legendary 1-2-3-4 Festival to London, combining exciting emerging acts with established favorites is a recipe completely in keeping with the ethos of Robomagic.”
