This compilation of the greatest sacred compositions for bass and organ finds it's ideal performers in singer Gunther Groissbock and Matthias Giesen on the Bruckner Organ in St. Florian. The repertoire spans from J. S. Bach through Haydn and Mozart to Bruckner and Brahms and ends with the conclusion of the oratorio "The Book with Seven Seals". Here, two of the most powerful instruments meet, not in conflict, but complementing each other to create a sound experience of exceptional quality. Three centuries come to life in the great Basilica of St. Florian, radiating their brilliance within the unique acoustics of this exalted church. Clemens Horak, Manuel Huber and Wolfgang Vladar, all members of the Vienna Philharmonic Orchestra, complement the outstanding duo Groissbock/Giesen as instrumentalists.
