 'rebetes (Greek: ρεμπέτης). Rebetes were unconventional people who lived '
 'outside the social order. They first appeared after the Greek War of '
 'Independence of 1821.\n'
 '\n'
 'The songs, often compared to genres like American blues, are full of grief, '
 'passion, romance, and bitterness. They are generally melancholic songs '
 'telling of the misfortunes of simple ordinary men. Many early rebetic songs '
 'were about drugs, especially hashish which led Rebetiko to be criminalized '
 'after the dictatorship of Ioannis Metaxas in 1936.\n'
 '\n'
 'Not until 1947, when Manos Hadjidakis introduced Rebetika to the upper '
 'classes, were these songs accepted as a music style. Damianakos Stathis '
 'noted that the rebetic songs of the first period were mostly the singing '
 'expression of "lumpenproletariat". ')
