The complete works of the early 15th-century Burgundian composer Reginaldus Liebert are contained on this disc, and an impressive legacy it is. They comprise a polyphonic "plenary mass" (likely sung at Cambrai Cathedral in 1425), along with a concluding Kyrie for four voices.
"This is the third of Kevin Moll's superb releases for Lyrichord with his Discantus group…. The writing is elegant, accomplished, and hypnotically fascinating…. All blend in a vibrato-less cohesion of ensemble that, matched with excellent energy and rhythmic vitality, recreates this potentially austere music with great beauty…. Liebert's masterpiece belongs to the first stage of the Mass's emergence as the supreme form of art-music composition in the final heyday of Gothic civilization, on the threshold of the Renaissance. We have had few recorded examples from this stage other than Dufay. Collectors of early music will ignore this at their peril. Glowing recording sound; elaborate notes, with texts and translations."—American Record Guide
