The only artist my family could all agree to go see was James Blunt, so I got to see him on Back to Bedlam's tour. It was a good show, Blunt is self-aware and often joked onstage (stuff like, "I'm at the piano, so you know it's going to be a sad whinge of a song next").
First solo concert was either Cannibal Corpse or Alestorm, I can't remember which show was first.
