Koutus is a Finnish musical collective led by accordionist Harri Kuusijärvi. Drawing on various contemporary influences the group creates a distinctive soundscape with taste of prog rock, jazz and world music fueled with improvisation – avant-fusion-accordion-jazz, as it has been described. Kuusijärvi's compositions present accordion in a new light accompanied with varying lineups of unconventional instrumentations.

The albums Koutus (2014) and Music For A Family Picnic (2017) have been internationally acclaimed by critics of jazz, rock and world music. Third album Mirage will be published in 2020 by Eclipse Music.
