MUZSIKÁS is the one of the most popular and most renowned ensemble in Hungary and worldwide playing the traditional Hungarian folk music. The members of the group play and improvise in the style of old traditional Hungarian village folk bands. They appeared at famous concert venues of the world as the Royal Festival Hall, London, the Theatre de la Ville, Paris the Concertgebouw, Amsterdam or the Carnegie Hall, New York. They are awarded the prestigeous Hungarian State award for artists, the Kossuth Prize and they are the winner of the WOMEX Award 2008, the most important international award for folk musicians. Their relaxed performance this evening is an introduction to the rich, hidden traditions of the Hungarians. www.muzsikas.hu
