Tim Raymond's dramatic and inventive organ piece was composed for the instrument in St Bavo's Cathedral in Ghent, Belgium, and was inspired by a plainchant melody found in a manuscript compiled there in 1481. Atmospheric, mysterious and fluid textures alternate with energetic, toccata-like passages, reflecting and transforming the pitch structures and temporal proportions of the chant - a meditation on the Trinity. A further dimension connects and resonates with the colourful pantheism and cosmic symbolism of the Van Eyck brothers' famous fifteenth- century altarpiece, The Adoration of the Sacred Lamb, created for, and housed in, St Bavo's.
