This weekend sees Radio 1 holding their huge weekend in Hackney with everyone from Jay-Z to Kasabian descending on East London to party.

With the best in pop, rock, hip-hop and R n' B represented we have rounded up the twenty acts you have to see if you are one of the thousands lucky enough to get free tickets to the event.

Kicking us off is Nicki Minaj (below) making a rare live appearance in the UK, Nicki will be sure to put on a spectacle to remember as well as treating the people of Hackney to her hits 'Super Bass' and Starships'.

Check out the full twenty, including stage and individual day details, below:
