Hes headline or bust I think. He recently played to over 100,000 people at Rock In Rio and is headlining every festival he is announced for so far and supposedly headlining Sziget. He just doesnt feel R&L to me especially with his new album being less pop and more singer songwritery/folk/ country sounding.
He can sell a lot of tickets but I dont think we have a festival here that will book him.
