To mark and celebrate the thirty years of the INA (Institut National de l'Audiovisuel), the GRM (Groupe des Recheches Musicales) has chosen to bring together an exceptional set of five compact discs, illustrating some of its most remarkable musical archives. These original works, which are often previously unpublished or have been dispersed throughout a host of other publications, are important because of the originality and audacity they testify to in the second half of the 20° century. Some listeners will be pleased to see that there are a number of illustrious composers here who, in the 1950s, frequented the studio of Pierre Schaeffer, and others will discover numerous musicians whose enthusiasm enabled this innovative musical genre to last throughout the following decades.

from the attached booklet

Here we have a splendid ensemble directed by Mackerras, with top-notch singers headed by Adam, Schreier, Mathis. All are terrific baroque interpretors. The full religious sense and up-lifting spirituality are being fully realised. Theo Adam is one of the best bass bartione voices for the Messiah (the other being Donald McIntyre, in his recording for Karl Richter). His arias are powerful, dramatic and uplifting. Peter Schreier is without doubt the best tenor ever to grace the arias of this great oratorio in German. Edith Mathis sings the soprano parts with such zeal and conviction that lifts this performance from the purely artistic level to a religious level. (Amazon)
