The richly varied concert piece shows how well the composer, himself a brilliant piano player, knows how to use the instrument. His polyphonic, complex compositional style gives way to various possibile interpretations. Despite high technical demands, the entire work is comfortable to play. A beginning appearing from nowhere which, with its consistent basic rhythm, reveals Jost's passion for jazz music, gradually becomes more intense. Eventually, the music changes into a softer, lyrical passage, allowing time to breathe. At the end, motifs from the beginning are taken up again. And after a phase of great intensity, the work fades into nothing.
