Being born into a culture will most likely help one interpret and perform the music of that culture but to say that no one else can "do it well" is not only patronizing but also untrue. There are just to many examples to the contrary to substantiate that theory. Do most Latin musicians play Latin music better than their non-Latin counterparts? I'm guessing ABSOLUTELY, but that doesn't mean that someone else that is dedicated to learning and performing this type of music still "can never do it well". JMO.
