Justin Timberlake Debuts New Music In London At iTunes Fest

Justin Timberlake took the stage at the iTunes Festival in London on Sunday to perform tracks from The 20/20 Experience - 2 of 2. JT opened the set with his newest single entitled "Only When I Walk Away" before dropping a medley of "T.K.O." and "Holy Grail" - the opening track from Jay Z's Magna Carta Holy Grail LP featuring Justin's raw performance on the hook. His amped up performance at London's Roundhouse was the perfect precursor to the release of his latest LP, which drops today. The month-long iTunes Festival boasts 30 nights of free music.
