Missa De plus en plus / Missa Au travail suis

Missa De plus en plus / Missa Au travail suis is a compilation of two masses by the Franco-Flemish composer Johannes Ockeghem, composed in the mid-15th century. These large-scale sacred works exemplify late medieval to early Renaissance polyphony, characterised by dense contrapuntal textures, pervasive imitation and expansive vocal lines that illustrate Ockeghem's place in the development of Franco-Flemish sacred music.
