Even heathens surely cannot help but enjoy to the bottom of their soul the sacred a cappella choral music of Jaakko Mäntyjärvi.

The carefully customised tonal colours are delicious, so much so as to be sinfully seductive. The Choir of Trinity College Cambridge gives a spot-on performance. The sopranos are celestially bright and pure, and the basses can descend to any depths on demand. Stuttgarter Psalmen has an Old-Testament austerity to it; the unison opening of the first movement, ‘Warum toben die Heiden’ (Why do the heathens rage), is thrilling. The Trinity Service is in a more restrained idiom, as befits its function.
