Tuuletar prove that four voices are all you need to build an entire sonic universe. Drawing on ancient runic songs and traditional poetry, then supercharging them with beatbox and contemporary pulse, the Finnish quartet have coined their own brand of “vocal folk hop”, at once ancestral and physical. Internationally acclaimed, their sound even echoing through a Game of Thrones trailer and several Netflix series, they turn every breath into rhythm and every harmony into a collective trance.
