Corresponding with Trio Mediaeval"s tenth anniversary, their fourth ECM album is a powerful and compelling recording of Norwegian folk songs. Performed in concert over the years, these songs are always received ecstatically - this is the album that Trio Mediaeval"s fans have been waiting for. The infectious melodies and haunting harmonies of this music will communicate across categories to a very broad listenership. Joining the trio on several selections is percussionist Birger Mistereggen, a specialist in the Norwegian folk drumming tradition. The inclusion of percussion not only widens the sonic spectrum of the group, but also adds a rhythmic element to these ballads, hymns, psalms, love songs and lullabies. Founded in Oslo in 1997, the Norwegian- Swedish vocal group Trio Mediaeval was taken up the following year as protégés of the Hilliard Ensemble. Hilliard tenor singer John Potter was especially excited by their potential and brought the group to ECM, acting as producer or coproducer on each of their New Series discs, Words of the Angel, Soir, dit-elle and Stella Maris. Each of these recordings has had great success with fans and critics alike and the trio has maintained a consistent touring presence in the US and all over the world.
