I have 2 worst concerts I ever went to.
First: Ozzy Osborne at Jones Beach in 1996. I remember getting these tickets for a guy I was seeing who loved Ozzy. I just remember that I took several trips to the ladies room, just to escape the noise! I really hated this show!
Second: 2006, Lynyrd Skynyrd at the Taj in Atlantic City. To make it brief, I was bashed on the head, practically knocked unconcious in the front row at this concert; right in front of a security guard, who did nothing to help me! I was so shaken up & traumatized by this experience that I didn't attend a concert for 2 years after this. Make no mistake, security is not there to protect you, they are there to protect the band only! This resulted in a criminal assault charge & a lawsuit that shook me to the core! Thankfully, I'm over it now, but beware of all the drunk people around you.
