This duo plays improvised music; Hvizdalek uses only voice and microphone, although with her voice techniques it may sound like something else entirely, while Fetveit uses primitive electronics, as the voice can sometimes sound like. Their playing with the similarities between pure voice and pure electronics gives a musical tension and a distinctive sound.

The couple is happy to go to the extreme, either reducing or exploding soundwise. Not so easy to say what happens before it happens, but easy to say that it does not happen with a four quarters beat.

Hvizdalek originates from Viennaโ€™s improv-environment, while Fetveit started his noise experiments in Oslo in the early eighties.
