Quetsch 'n' Vibes combines different musical worlds. The folk music embodied by the Styrian harmonica blends skillfully with the jazzy sound of the vibraphone, the earthy sounds of the marimba and many other exotic instruments. From this encounter arises a flow of new sounds and colors, on which the trio skilfully navigates between the different musical worlds.

Nomfusi is a multi-nominated Afrosoul singer from South Africa. Wherever the petite singer takes the microphone, superlatives are not far away - the charm, the voice, the energy! With her mix of groovy township sounds, Afro-soul and Afro-pop, paired with incomparable stage presence and a gigantic voice, the daughter of a South African sangoma (healer) captivates audiences worldwide. With ease, she interweaves the essence of Africa with jazz, soul and her Xhosa culture, to the Maskandi sounds that resonate from the green hills of the east coast. Nomfusi is a true musical jewel who, together with her four-piece band, takes hearts by storm and radiates a fabulous energy. An energy that you cannot escape and that reawakens the joy of life.
