Many DJs try live acts. Promoters are willing to pay more for a one hour live act, versus a DJ set. That said, many many many good DJs and producers are crap in live acts. Most of these live acts are boring. Somehow these producers, able to create cool tracks in their studio, can't do this in real time. I'v heard so many live acts in my live, but only a few I cold handle more than half an hour. Live acts are definitely a skill and only a few actually master this skill.
