Is it safe to go to concerts anymore?

I'm asking a serious question. First, Kid Cudi attacks fans and now Mario is punching the sound guy. What's really good?

Word in the blogosphere is Mario attacked the sound engineer after he cut the power and lights after Mario went over the allotted time slot at MusicFest. This resulted in Mario being escorted out by security.

Mario sent out this tweet via @mariosoultruth: I can't explain, somethings just happen on they own... about 21 hours ago via UberTwitter.
