Rebetiko probably originated in the music of the larger, mainly coastal cities in today's Asia Minor with large Greek communities during the Ottoman era. In these cities, the cradles of rebetiko were likely to be the hashish dens and coffee shops, and even the prison. There is a certain amount of recorded Greek material from the first two decades of the 20th century, recorded in Constantinople/Istanbul, Egypt, and in America, of which isolated examples have some bearing on rebetiko, such as in the very first case of the use of the word itself on a record label. This podcast series delves into the music from the underground that changed the musical landscape of Greece forever.
