"I've been in the studio working on some new music, and I thought tonight would be the perfect night to play something new for you," Alicia Keys said before launching into a stark, soulful ballad called "A Place of My Own" at the iheartradio Music Festival in Las Vegas on Friday night. The song, an urgent, piano-pounding number in the style of Adele's "Rolling in the Deep," sounds like a smash hit waiting to happen.
