Local Suffolk Boy Ed wants to give 3 bands the chance to play to a crowd of 45.000 at his Ipswich homecoming gig.
The singer is to end his two-year tour supporting his Divide album with four gigs in Chantry Park, Ipswich.
BBC Introducing in Suffolk has been asked to pick an act for each of the first three nights of the August dates.
Ed grew up in Framlingham and earlier on his career was given gigs at Harvest at Jimmy's Festival in 2010.
The acts will be chosen from those who have added their music to the BBC Introducing Uploader website by Thursday, 4 July.
The three local artists will be picked to play a 20-minute opening set at the sold-out gigs on 23, 24 and 25 August. The opening act for the final night of the run will be selected by local skateboard company Hoax, via a national battle of the band's competition.
The Darkness, who also hails from Suffolk as well as Lewis Capaldi and Passenger has been announced as the other supports.
