Festival takes music deep into Istanbul's centuries-old heritage  

It's an early summer evening at Istanbul's Grand Bazaar, the maze-like warren of alleyways crammed with shops that has been the city's trading hub for over half a millennium.

Nor is the air filled with the pungent whiff of oriental spices being offered to passers-by.
