Stephen Bulla's ‘Caelum Corona' (‘Crown of Heaven') portrays, in sound, a Christian's walk in faith, intended metaphorically via a musical narrative reminiscent of the early church pilgrims, their struggles and triumphs. The composer initially evokes the atmosphere of Rome at the time of St. Paul and other martyrs, thus the Latin title. Bulla marks his imaginative tone poem with dark, brooding music in the first two of three parts, in each of which he has embedded an appropriate hymn or song reference as thematic material.
