The Fortuna/Dys duo is known primarily for their achievements in jazz and improvised music. They embrace combining styles to engage the contemporary, young listener. A pupil of Nadia Boulanger, a friend of Arthur Rubinstein, and "a star amongst the students" according to Lutoslawski, Roman Maciejewski would eventually "relinquish the more glittering and at the same time superficial life of an artist with 'a career' in order to continue work in my appropriate field with the complete determination and inner peace." The tracks "Eco", "Drommen" and "Fjattrad" are among those of Maciejewski's compositions which had never been published.
