That's a greatest hits collection of choral music, great for beginning collectors. I think I may have too many CDs, because I have virtually all those works, some in multiple performances, excepting perhaps some of the odds and ends on the final disc.
I think I saw only one Haydn mass listed there. All six of his late masses should be in the collection of
every classical collector. All six are towering masterpieces. H. C. Robbins Landon, the great Mozart and Haydn scholar, thought that the "Nelson Mass" is arguably Haydn greatest work. In particular, my favorite may be the "Mass in Time of War" in the Kings College Choir performance, but the CD transfer is second-rate. I have three or four back up performances in better sound. The first six masses are much earlier works, but like almost all of Haydn's music, they are pretty wonderful, too.
Masses nos. 9–14 form a group: each was composed by Haydn for the Esterházy family, to celebrate the name day (12 September) of Princess Maria Hermenegild, the wife of Prince Nikolaus II and a friend of the composer.[2] The composition of these masses was Haydn's principal duty to his old employers at this time of his career.
