I didn’t feel safe – that was the first time I genuinely became scared of dying, because you just didn’t know whether a rival cartel would turn up and a fight would break out, or if the police would burst in with guns of their own. Neither of those things happened, but I knew from seeing cartel turf wars on the news it could happen. But, weirdly, I also felt quite protected because of all the security. And, in some ways, hanging out with these guys was fun – if I tried to forget who they really were. Once I’d started doing the concerts, they’d take me and my colleagues to fancy places for dinner and drinks. But I was always aware one of them could shoot me if they wanted to.
