I saw him on a local Christian stage for a concert we have once a year. His music was awesome, but he was very angry at people who were wanting his picture or autograph. (as you know, many kids do) I would say that he is extremely passionate and authentic. Which I much admired... He was accusatory when it came to calling people out and saying they have no clue (with conjecture)....abrasive...as those who are passionate sometimes do. But, his love the Lord was/is O so evident! Love his music...awesome lyrics that make you think and awesome praise to the Lord!!
(this to say: if you go to see him in person...be prepared for major angst...BUT it is worth it!)
