When he reappeared, he found himself in a crowd of people (mostly Goths) jumping up and down and screaming. The people were so loud and the music was so deafening that Jon found it hard to concentrate.
He moved towards a less crowded area of the concert, almost toppling over once or twice on his way.
Once he made it, he had a clear view of the stage. And right in the middle was his father, dressed only in a nylon shirt and black leather pants and boots. His hair was spiky and his skin was pale white and covered in tattoos. And in his hands, he held an electric guitar.
This was most definitely not the father he knew.
