The new organ system in Mainz Cathedral, inaugurated in August 2022, is internationally unparalleled in terms of its conception, construction, innovation, quality of craftsmanship and tonal nobility: an absolute centenary project of organ building for the thousand-year-old Mainz Cathedral! The present programme, some of which was produced as a live SACD (stereo and 5.1 surround), was assembled on the basis of the works performed at the inaugural concerts. At its centre is the nearly 30-minute organ sonata in C minor "Der 94. Psalm" by the Liszt pupil Julius Reubke. Cathedral organist Daniel Beckmann, a decisive contributor to the concept of the new instrument, brilliantly demonstrates the new possibilities of this fascinating cathedral organ.
