The crystalline voices of Trio Mediaeval have captivated audiences since the group was founded in Oslo in 1997. The Grammy-nominated trio’s core repertoire features sacred monophonic and polyphonic medieval music from England, Italy and France; contemporary works written for the ensemble; and traditional Norwegian, Swedish and Icelandic ballads and songs. The group’s fruitful relationship with the legendary ECM Records, collaborative spirit, and busy touring schedule has earned them worldwide renown. “Singing doesn’t get more unnervingly beautiful,” wrote Joshua Kosman of the San Francisco Chronicle, who declared their San Francisco debut “among the musical highlights of the year.” He added, “To hear the group’s note-perfect counterpoint – as pristine and inviting as clean, white linens – is to be astonished at what the human voice is capable of.”
