The vocal ensemble Lumen Valo is one of the top ensembles in the Finnish early music scene. Since their debut in 1993 the group has specialised in unaccompanied Renaissance music. Their repertoire covers also the late Middle Ages, early Baroque and contemporary music. The ensemble performs regularly in Finland, Europe and the United Stated. They have released ten CDs, the latest seven of which on their own label Sigillum. Lumen Valo has also appeared often on television and radio.
