Dervisia: Jan Verdonk (bouzouki, vocals) Alexandros Kyrkos (guitar and vocals). We play Rebetika and Smyrnaiika songs from the beginning of the past century, with authentic sound. Rebetika songs are the 'Greek blues' and were developed the beginning of the previous century in Greek urban centres all around the Aegean sea. They were associated with a marginal bohemian subculture and it took time until they came up ground, as the lyrics are often related to underground issues like drug use and jail culture. Smyrna is a city at the east coast of the Aegean sea and was an important Greek cultural centre until 1912. A cosmopolitan air and an authentic musical fusion of oriental elements with western music and Byzantium traditions.
