The song he performed was a bit of a diss song towards the Mexican Cartels... not sure if it was El Chapo or not, but it was definitely not speaking highly of them.Why they kill him? Was he talking shit about the cartel?
Anyway he was told before even going to that town/venue to perform not to come, and if he did come he had better not perform THAT song.
He went anyway. He performed that song anyway. As soon as the beat dropped they handed him a note, he read it, took a deep breath and performed it anyway... he tried to call their bluff and it didn't play out in his favor
