Lady Gaga is set to deliver the keynote address at the music portion of the South By Southwest festival next week (beg10Mar14). The Poker Face singer is already due to perform at the event in Austin, Texas on Thursday (13Mar14) and she will speak to Music and Platinum registrants at the festival at the Grand Ballroom of the Hilton Austin on Friday morning (14Mar14). Gaga will perform at the Stubb's Doritos #BoldStage after being denied a permit to sing at the Doritos stage's original venue because organisers deemed her plan to play in a huge vending machine too dangerous for fans. The performance will benefit the singer's Born This Way Foundation. Dave Grohl delivered the keynote speech in 2013.
