Celtic Roots Ensemble is a mix of broadly experienced musicians: Knut Reiersrud, Aly Bain, Ale Möller, Tuva Syvertsen, Frasier Fifjeld, and Olle Linder. These musicians from Norway, Sweden, Scotland, and Shetland play various guitars, harmonica, mandola, trumpet, flutes, harmonium, bagpipe, harding fiddle, percussion, and double bass – to name but a few.
The ensemble was put together to make a recording for the Jazz at Berlin Philharmonic series, in which music that has influenced the European jazz tradition through various musical directions is presented.
The result was the live album Jazz at Berlin Philharmonic VI: Celtic Roots, that emphasizes the Celtic music's imprint on European music and American folk music and blues, and was highly acclaimed within the music field.
At Festplassen, traditional folk tunes from Scandinavia, Scotland, and Shetland are intertwined with an American blues sound at its base.
