Speaking as someone else who has seen James live, I highly recommend going if you have the chance. I agree with debrod, these videos do not do his voice justice. He has an incredible live voice, one of the best live rock voices I’ve heard in many, many years. The only thing better is his stage presence, absolutely commanding. I think you are either born with that kind of ability, that “it” quality, or not.
I”m dying to seem him live again, and I hope the tour for the new album brings him and the band near me.
