Encase you haven't heard the news the allegedly now sober Amy Winehouse recently played a rather unsuccessful gig in Belgrade. And by "unsuccessful" I mean car-crash, as demonstrated by the opening number.
But I'm not going to hawk over this one, as Amy is clearly in need of some serious help, and I'm not going to discredit her talent based on this performance as her recorded career shows that she can sing. However I am going to ask "Is anyone really surprised?" as it's hardly the first time she's been wrecked at her performances and wasted the audiences money. She's been caught sniffing drugs, falling over and not singing many times before; this is hardly a one off incident and, as long as people keep on buying tickets to her shows/enabling her, it's unlikely to be her last.
The simple truth of the matter is that Amy Winehouse isn't that good at live performances and everyone knows it, including her fans. She has a well deserved reputation for being awful at her own shows so you're options are either to not bother seeing her live (though carry on getting the albums and catching her one-song TV appearances if that's your thing) or to pay your money and take your chances whilst remembering to not moan when it all goes horribly wrong. Also remember that there are normally no refund clauses for "show went ahead but singer was too trashed to be any good", though there is for cancelled shows so get ready to claim if the rest of the tour goes up in smoke. I'm not going to say that there is anything wrong in liking Amy Winehouse but don't be blind to her flaws.
