For hundreds of years now the island currently known as Sri Lanka has had a thriving musical culture (or cultures, not to politicise the issue). There’s been folk music for as long as there’ve been folks. The various strata of society have refined their ceremonial music, be it sacred or profane. Each ethnic group in each part of the island has hived off its own sub-genres over the centuries. And in the colonial era (eras) a whole new batch of influences arrived, fully formed, ready to be adopted wholesale or adapted and integrated for local use.
