A typical Machine Gun Kelly show is one where you fear for his safety. The Cleveland-born rapper climbs things he shouldn't, crowd-surfs standing up, and hangs off uncertain scaffolding. So naturally the Bad Boy signed with Diddy. (Don't hurt yourself!) He's also recently traded verses with DMX ("I Don't Dance") and held a chainsaw on XXL's 2012 Freshman cover. Safety is not an option.
