Tinie Tempah, Lawson and Avicii BUT NOT LADY GAGA YET have all been added to the lineup for next month's iTunes Festival in London.
Tinie will perform some songs in an aggressive fashion on September 26, while Avicii will stand behind some decks and wave his arms around on the September 13.
Lawson have the honour and privilege of performing before Jessie J on September 23.
All the 'gigs' will be at the Roundhouse in Camden, but don't let that put you off, it's quite a nice venue.
The September 1 headliner has not yet been announced.
