The young Argentinian conductor was first interested in composing. He studied both composition and conducting at the university in his home town of Buenos Aires. Nowadays, Alejo Pérez regularly works in his home country, as well as in Europe with major orchestras and ensembles.

In the 2010/2011 concert season, Alejo Pérez was invited to be guest conductor and music consultant at the Teatro Real Madrid where he has since regularly performed with the Orquesta Sinfónica de Madrid. In 2012, he was hugely successful with the concert version of Wagner’s Rienzi. A formative period at the start of Alejo Pérez’s career came with his appointment as Christoph Dohnanyi’s assistant with the NDR Symphony Orchestra from 2005 to 2007. In subsequent years, he has conducted, among others, the Royal Stockholm Philharmonic Orchestra, the Orquesta Sinfonica Nacional de Chile and the Dresdner Philharmonic Orchestra.

Between 2009 and 2012, Alejo Pérez was musical director of the Teatro Argentino de La Plata, bringing it to new success. Praised by the press and audiences alike, he produced great works of the opera and concert repertoire.

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‹.
