Zelenka's output contains mostly sacred music. His instrumental works, however, show the composer's talent and shouldn't be overlooked. The work included on this release, Sonate a due Hautbois e Basson con Basso Continuo, ZWV 181, was written in Vienna between 1715-1716. The work is notable in double reed literature for the required virtuosity of both instruments, which was uncharacteristic for the music of that time. This release is the first recording from the ensemble Zefiro. The featured double reed performers are oboists Alfredo Bernardini and Paolo Grazzi, and bassoonist Alberto Grazzi.
