I am not sure I understand your objections to the Rough Guide as a reliable source Nowhere on Wikipedia can I find anyone questioning it I would so go far as to say that the Rough Guide to World Music is an excellent English language source for information about this artist And I can assure you that the book does mention Tatl ses and his ancestry Please provide a link that supports your argument Moreover there are no contentious claims being made about Tatl ses He himself admitted to being a Kurd in front of millions of Turkish television viewers in December of 2003 I have provided a source for this as well Please refrain from removing sourced information from the article Discuss further controversial changes here first As you can see from the other discussions above the topic of bo s background has been covered ad nauseam Regards
