This unique collaboration of voice and piano trio got off to a flying start with a series of concerts featuring Scottish and Irish folk song by Beethoven in the original adaptations for baritone and piano trio. Beethoven was one of the few composers to write music for this combination. Koningsberger & Atlantic picked up the musical thread, building three different programmes and adding numerous new arrangements for baritone and piano trio to the repertoire (Ravel, Vaughan Williams, Copland, Butterworth, Schubert and more), written by their pianist Bas Verheijden. Their programs are one-off because of the extraordinary use of colors and instrumentation. In 2018 they released the album Old Songs Re-Sung on the label QUINTONE available on Spotify The latest project features Schubert Lieder in new arrangemenst for baritone and piano trio.
