Fr Guido Haazen was a Franscian friar (monk) from Belgium who worked with a choir from the Congolese town of Kamina.
The original recorded release had Congolese songs on Side A, and the Missa Luba on Side B. The mass was published in 1969, and is based on various influences:
Kyrie – kasala (Luba song of mourning)
Gloria – Kiluba-style improvisiation from Katanga
Credo – five folk songs linked by improvisation, including the customary announcement of death, first on the kyondo (log drum), then on the kikumvi (tom-tom), followed by the kilio (elegy) sung by the solo voice.
Sanctus and Benedictus – Bantu farewell song.
Osanna – rhythmic dance of Kasai
Agnus Dei – Bena Luluwa song from Kananga
The Missa Luba has been used in various formats – the film The Singing Nun (1966), If (1968), Deadly Voyage (1996), Lost and Delirious (2001) and Never Let Me Go (2010).
A good follow on from this would be the 1964 Missa Criolla by Ariel Ramirez:
