The timeless chants of the Gregorian chant in contrast to the transience of the improvisation by jazz saxophonist Jürgen Seefelder, which emerges from the moment - this tension is the source of the live recording of a concert by the ensemble officium in the cathedral of the city of Worms.

Chants from the mass alternate with prayers, psalms and hymns from the Liturgy of the Hours. Some of the music is overlaid by the improvisations of the saxophonist, others are taken up further or contrasted by something completely new. Worms Cathedral proves to be the ideal sound space for this meditative sound experience.
