This episode will give the listeners an umbrella introduction to Rebetika.
What is Rebetika?
Often called the Greek blues, like the blues, it grew out of a specific urban subculture and reflected the harsh realities of an oppressed subculture's lifestyle. Although the origins of the music certainly stretch into the 19th century—and earlier— it was especially important and vibrant during the 20s, 30s, 40s, and early 50s. It was the music of the lower ends of the socio-economic spectrum—those who stood outside “mainstream” culture in certain although not all respects.
