Mary J. Blige will perform a gig with MasterCard this month, singing a host of her iconic hits and songs from her latest album The London Sessions.

The intimate gig will be held exclusively to an audience of around 400 at One Marylebone Road on Wednesday 24th June and Mary has revealed that her set will feature the biggest hits from her London Sessions album as well as some of her classic songs. The gig falls just ahead of the Glastonbury Festival where Mary is also due to perform.

The gig is part of MasterCard’s Priceless Surprises campaign that has seen a number of iconic artists including Mary J. Blige, Usher, Pharrell Williams, Kaiser Chiefs and Paloma Faith surprise their biggest fans and bring them closer to their music. Mary surprised lifelong fan Rana earlier this year when she flew in from New York for a personal performance.

Mary J Blige commented: “I’m a huge fan of London - it’s been a big inspiration to my music and it’s going to be great to be back in the city where I recorded my last album. The last time I was here I performed for one very surprised fan, so this will be a chance to share an amazing experience with more of my British fans.”

Fans can enter to win tickets to Mary J. Blige’s gig and keep up to date with details of the other Priceless Gigs taking place this summer at
