Berlin Philharmonic bass trombone player Stefan Schulz is one of the foremost exponents of his instrument. His second BIS disc, Copenhagen Recital, opens with a quartet of Russian songs, exposing the yearning, melancholic side and melodic potential of an instrument usually associated with music of a more overpowering nature. What follows is a varied program, taking in Telemann's F minor Sonata, Robert Schumann, Lebedev’s Concert Allegro, works by two living composers, Daniel Schnyder and Søren Hyldgaard, and encoring with an arrangement of Thora Borch’s 1866 song The Sky Darkens.
