Worst concert experience for me was a KISS concert. They sucked live. They claimed to be the starters of music theater. Pink Floyd used pyro regularly as of 1971/72 with the infamous exploding gong on Set the Controls and the explosions on Careful With That Axe plus fireworks when they played outdoors. They added a crashing plane which ignited on the DSotM tour in 1973. Animals had the pyro showers on Sheep, an exploding pig and fireworks at the end of each gig. KISS are pretenders to the throne!
