Folk

Each country has, by definition, its own folk music, hence: World Music. Nevertheless, the traditions having the most influence on Western popular music are those of the UK (Fairport Convention since 1967, The Unthanks in the 21^st century) and the US (Woody Guthrie, Joan Baez, Buffy Saint-Marie).

But as noted, Folk is music of the world, so travelling—or listening widely—might connect you with something from Africa (Ladysmith Black Mambazo), Ireland (Mary Black or The Pogues) or, closer to home, Australia’s Gurrumul Yunupingu.
