The fusion of the ancient lyre sound blended with voices will be enhanced by the mandolin melodies played by Vassiliki, while the minimal sounds of the accompanying percussion will contribute an archaic simplicity to the performance. The songs will unravel through the blue notes of the ancient lyre starting from ancient music and reaching out to traditional and contemporary compositions; from the blues to "zeybek" (a form of folk dance peculiar to western, central and southern Anatolia), from ancient Greek and modern Greek songs to Turkish folk melodies, weaving a rich embroidery characteristic of the Aegean and the Anatolian hinterland.When: May 10 at 8 p.m. Akbank Sanat Contemporary Vocal Days ends with Yinon Muallem and Guy MintusComposer and percussion virtuoso Yinon Muallem, from Istanbul, will close the event with young American jazz pianist Guy Mintus on May 27.
