I had only heard a few selections by this composer, so was unfamiliar with his work. This 2 disc album is a great introduction to his music, both his instrumental & sacred works. His Choral Works are beautiful. Sung in Latin as well as in the Slavonic language of the Orthodox Liturgy, which I assume would be Russian. Unfortunately I cannot distinguish between Estonian & Russian. I highly recommend this CD. His music is a delight to listen to.
