Tsuumi Sound System is an energetic eight-piece ensemble, which fuses the nuances of various forms of world music with Nordic folk tradition. Formed in 1998 by accordion player Hannu Kella as a backup band to the Tsuumi Dancing Group, the ensemble has in the meantime celebrated numerous successes of its own.

Diversity is an essential characteristic for Tsuumi Sound System, along with carefully crafted compositions and intense live performances. The band describe their sound as ›Finnish Urban Ethno‹; together with a pinch of Balkan folk, some Latin edge and good portion of jazz, a talent for delicate nuances rounds off their repertoire.

In 2008, the band made a guest appearance at ›Summer in Lesmona‹, and in the festival’s 20th anniversary year in 2014 again delivered an acclaimed performance.

 The line-up features Hannu Kella, the lineup features Pilvi Järvelä (piano, harmonium) as the only female band member in the octet, as well as Tarmo Anttila (double bass), Tommi Asplund (violin), Joakim Berghäll (saxophone, percussion), Tero Hyväluoma (violin), Jani Kivelä (guitar) and Jussi Nikula on drums.

In 2013, Tsuumi Sound System released their sixth album ›Floating Letters‹.
