Szilard Mezei was born on February 12th, 1974 in Senta, Serbia (then Yugoslavia) as a member of the Hungarian minority in the multiethnic region of Vojvodina.

His orchestra plays contemporary improvised music, mostly performing his own compositions. As a composer, Mezei is interested in exploring the relationship between improvisation and composition (similarly to Witold LutoslawskI aleatoric and Anthony Braxton's creative music methods), incorporating elements of jazz and authentic folk music as well. As a young musician he followed the path of B.Bartok and Gy.Szabados. Mezei is also very actively involved in composing scenic music and plays authentic Hungarian folk music on genuine folk instruments (koboz and oud).
Since 2001, Mezei is closely collaborating with choreographer Josef Nadj, director of the 'Centre Chorégraphique National Orleans in Orleans, France. Their mutual project 'Les Philosophes' was selected theatre-piece of the year 2001 in France. The play was performed with great success at the Festival of Dance in Cannes, France 2001, in Avignon 2002, in Brugge (Belgium - the capital of European Culture for the year 2002), in Orleans in October 2002, in Paris in May 2003, in Reggio Emilia (Italy), in Le Havre, in Nantes (France) 2004, and in London 2005. In 2006 they collaborated on a new project 'Asobu' (together with co-composer Akosh S.). This play was premiered at the Festival Avignon in 2006, then successfuly toured Europe and Japan.
In 2003 Mezei was invited by the Creative Workshop Ensemble of Denmark to tour in that country, performing some of his compositions.
