Le Jeune's mass is the most impressive polyphonic monument of the late Renaissance, combining tradition & innovation within an idiom which was soon to vanish. It's a fine piece, with a large number of original contrapuntal ideas, as are the Magnificat & Benedicite Dominum. Each is among my favorite c.1600 century sacred works.
These are all unique items, not to be duplicated repertory-wise.
The performance is quite good, with fairly good clarity and a wonderful tone. The use of instruments certainly aids intonation in demanding passages, but I reserve judgment overall.
