The percussion trio SISU was formed in 1993 and its primary aim is to perform Norwegian contemporary music.

As well as complementing traditional contemporary works with explosive and rhythmic music, SISU's members exploit the visual potential of a stage performance, often wearing unconventional concert attire, or playing unusual instruments. Their performance aesthetic comes from the realisation that percussion music requires a greater amount of physical effort and movement than many other forms of music - the audience sees what it hears. SISU works to integrate this into an audio-visual performance style.

SISU has performed throughout Scandinavia and Norway, including at the ULTIMA Oslo Contemporary Music Festival, and has also previously toured to South Africa and Germany.
