Petr Eben is considered to be one of the Czech Republic's leading contemporary composers. His organ compositions explore new territory in regard to playing techniques, sound and subject matter. His goal is to convey a message to listeners, through commentaries or - as in his Second Organ Concerto - by prefixing his scores with a motto. Formal clarity and understandability are a requirement for him. His music is characterized by free tonality that always includes tonal sections. Gunther Rost was able to win two prominent guest musicians for this CD: Tine Ting Helseth (trumpet) and Babette Haag (percussion).
