Singers and instrumentalists are equal partners throughout Adoratio, the 33-minute symphony for choir and orchestra that is the centrepiece of this recording. Sombre, dramatic and haunting, it is a ‘prayer story … about the false paths taken by men and nations and their requests for God’s help’, based on sacred texts – the litany, Psalm 22 and Chronicles II. Juris Karlsons trained as a sound engineer with Latvian Radio, which clearly contributed to his skill as a composer. These accomplished forces deliver a searing performance of a very powerful work. The shorter, beautifully crafted pieces that frame it are equally impressive.
