Feature: Greek rebetiko music rises from margins to UNESCO's list

Photo taken on Dec. 20, 2017 shows young street musicians performing rebetiko songs in central Athens, capital of Greece. Over a century since it was first played at cafes and tavernas of the poor on the Greek mainland and the Greek-speaking parts of the Ottoman Empire, rebetiko, dubbed the Greek blues, has now been inscribed on UNESCO's 2017 list of intangible cultural heritage.
