Istanbul has a deep, layered history. From its beginnings as a fishing village to one of the pillars of the Roman world. Across the centuries the city drew in cultures and blended them. Growing up there, singer-songwriter Gaye Su Akyol breathed all that in every day. Those rich traditions combine to form part of the sound she’s developed on her album Hologram Imparatorlugu (Hologram Empire), where sultry Turkish melodies twine around spiky, twanging guitars and insistent rhythms.
