Les Troubadours Du Roi Baudouin has been played on NTS in shows including This is Belgium w/ Nicholas Lewis, featured first on 23 March 2014. Songs played include Gloria, Lutuku Y A Bena Kanyoka and Dibwe Diambula Kabanda.

The Missa Luba is a version of the Latin Mass based on traditional Congolese songs. It was arranged by Father Guido Haazen, a Franciscan Friar from Belgium, and originally performed and recorded in 1958 by "Les Troubadours du Roi Baudouin", a choir of Congolese children from Kamina

The "Kyrie" and the "Credo" are wholly elaborated like the "kasalas" which are still performed according to the Ngandanjika (Kasai); the "Sanctus" and the "Benedictus" were inspired by a magnificent "Parting-song in Kiluba." The "Gloria" is improvised in the typical Kiluba-style of the Katanga. The "Hosannah" is a genuine rhythmic dance of the Kasai, and the "Agnus Dei" is a typical Bena Lulua (Luluabourg) song. Originally the music was not written. The composition was the result of general cooperation and of a spontaneous inspiration. Later, sheet music of Haazen's arrangement was published. In the "Credo" the text (the crucifixion and the death of the Redeemer) is preceded by the usual announcement of death, first on the Kyondo and then on the Kikumvi (Tom-Tom). Then follows a genuine "kilio" (elegy - dead-song) without percussion accompaniment, sung by the solo voice. The doleful tone is stressed by the repeated and sustained o-sounds ("… etiam prono … bis, sub Pontio Pilato… ). The Missa Luba was created by Baluba of the Kasai and Katanga, with Father Haazen.
