Ah yes, sorry. Read your message a bit too quickly. Doh.
One does get a bit confused with so many Diabates, Kouyates and Toures and Sissokos about. A bit like the great European musical dynasties of the 17-18th century (Bach, Couperin etc.).
PS: Sidiki was Toumani's father. The Cordes Anciennes is a bit of an old recording. Toumani's brother is Mamadou Sidiki. I tell you, it's just like seeing J.C Bach on a record and wondering which one of the tribe composed it.
PPS: according to my trusty Wikipedia, Mamadou Sidiki is of the 71st generation of kora players in his family.
PPPS: added a couple of links to the post above about Tiecoro, brother of Djelimadi. Generation 72 of the Diabate family is now ready too it seems (Madou's son, called Sidiki to make things simpler).
