"Our music is a response against narrow-mindedness and the mass culture that surrounds us, which in fact leads to destruction of human dignity," says Wojciech Krzak.

"The band is a radical turn to sources in search of musical inspirations and immemorial values."

Such descriptions may sound complex, but the sounds are gloriously light and uplifting.

Considering their craft "an inexhaustible source of fun, joy and spontaneity", the Warsaw Village Band formed in 1997 with a mission to help Poland find a new cultural identity after decades of communism.

Beginning their quest by learning songs from villagers in their native Mazovia region, they have remained resolutely true to their roots by playing exclusively acoustic instruments including thesuka, a unique Polish fiddle similar to the Indian sarangi.

"Our activity not only concentrates on music, but also focuses on everything which is associated with our Polish roots - especially what is condemned to be forgotten, yet can inspire and enrich contemporary culture," explains Krzak, the violinist.

"Our passion is travelling to small villages and visiting old musicians who tell us about their traditions, customs and ancient habits which are passing away.

"They hand down to us the part of this tradition in the form of music, which is the base and main inspiration for our further works."

With his mass of dreadlocks and inimitably bohemian dress sense, Krzak epitomises the beautiful weirdness of the band. It is a style entirely in keeping with their sonic efforts, which they attempt to summarise with terms like "hardcore folk" and "bio-techno."

Fronted by lead singer Maja Kleszcz, who bluntly admits that her vocal style is "close to screaming", the raw exhilaration and energy of second album People's Spring saw the band triumph as Best Newcomers in the Radio 3 World Music Awards two years ago.

Latest album Uprooting has also received widespread praise - as much for the passionate ideals exhibited by the players as the booming immediacy of the music itself.

"We are trying to create a new cultural proposition for the youth," declares Krzak.

"It's an alternative way to contemporary showbiz. That's our fight."
