The first demo is from Claude Bolling's Suite for Flute and Jazz Piano Trio - Versatile. The first part features the bassflute from VSL's new Special Woodwinds. The part after the double bass solo features the flute in C from the Woodwinds I package.
Second demo is an arrangement for contrabass clarinet from
Ralph Vaughan Williams' Six Studies in English Folksong - Adagio. Originally composed for cello and piano but performed over the years by many different instruments. This may be the world premiere of the contrabass clarinet version.
