I am glad I was able to see him once in concert. It was a really good show. That concert you went to with all of the concept work sounds a lot like the Bob Dylan show I went to. I thought it was going to be one thing, but it ended up being something very different. It as a little disappointing because of that.
Some artists are erratic and I've heard Dylan shows are variable. There's a lot of pressure for them to perform and it must be hard at times. Sometimes they may want to challenge the audience, but it's okay if you go in expecting that.
