Mirko Kolarić was a Croatian composer (born near the present-day borders with Slovenia and Hungary) of the early twentieth century. He was a Roman Catholic, and composed both Roman masses and Byzantine Catholic liturgical music. He narrowly escaped the Bleiburg massacre, but on returning home was brutally murdered by an acquaintance at the age of 35. As a result, he had not yet composed a large corpus of work, and he faded into obscurity. Apparently some of his music was banned for many years due to its Croatian nationalism, and only recently has there been a revival of interest in his compositions.
This setting of the Cherubic Hymn is certainly Romantic in character, but is quite pleasant.
