Jessie J performs at the 2012 iTunes Festival.

The 2012 iTunes Festival continued last evening with one of the UK’s most exciting young performers. Jessie J blazed the stage of the show with an extensive setlist of some of her biggest hits as well as her now popular cover of Usher’s ‘Climax’ and a special guest.

Included in Jessie’s J’s 90-minute iTunes Festival showing were renditions of ‘Mama Knows Best’, ‘Big White Room’, ‘Domino’ and ‘Laserlight’. Additionally, during her performance of ‘Price Tag’, the songbird summoned rapper Chipmunk to the stage to help her hype the crowd.
