Tim McGraw may have just released his latest album, "Two Lanes of Freedom," in January -- and capped off its accompanying tour with a performance at iHeartRadio Saturday night. But he's already begun work on the next record.
"I've actually been in the studio over the last couple weeks," McGraw said backstage at the MGM Grand Arena, as Paul McCartney played a rousing opening set. "I don't know when we'll have it out, but I've just been putting a lot of work that in that process where I'm sort of in the dungeon singing when I get the chance."
