Ulla Pirttijärvi & Áššu base their music on traditional Sami Joik. Ulla Pirttijärvi joiks about her relatives and her home villages Utsjoki and Angeli. Olav Torget and Harald Skullerud complement the ensemble with string instruments and percussions.
The ensemble draws further inspiration from West African grooves and tradition. Their expression varies from wide atmospheres and quiet moods all the way to more uptempo grooves.
The world music scene has long enjoyed their music especially around African and Arabic tradition. This has influenced the instrumental choices and unique sound of the debut album Áššu (Embers), out in Spring 2019.
