The estuary represents that astonishing space of transition and transformation where fresh water meets salt water, revealing unexpected potentials, much like the encounters imagined by Constantinople. The new collaborative Opus of kora master Ablaye Cissoko and the ambassador of Persian setar, Kiya Tabassian is the junction point where the rivers of their musical memories join the collective sea of the present moment. We witness a musicianship that bring them into a dialogue at the deep layers of musical conversations and creates for all a sense of wonder and awareness.
