Two composers. Two bassoonists. Two premieres. One big musical feast. The bassoon as a solo instrument does not appear all that often in the concerto literature, but a concerto for two bassoons is truly rare, being something that could arise only in the environment of an ensemble that possessed two soloists on that instrument. One such double concerto has been played for many years under the name of the important Czech composer Jan Krtitel Vanhal. But what if it had really been composed by someone else? The question has been raised by Ondrej sindelar, a player of the classical bassoon, who has found the same concerto bearing the name of Anton Zimmermann in one of Prague's archives. The two works differ from each other only in the slow movement. Theft? Plagiarism? A copyist's error? Collegial assistance? We are left with the unsolved mysteries of authorship and of whether the two masters may have met. Vanhal's travels took him from Hradec Kralove to Vienna, Italy, Hungary, and Croatia. Having established himself professionally in Hradec Kralove, Zimmermann went on to a successful career in Pressburg (Bratislava) in the service of Archbishop Jozef Batthyany. What is important, however, is that Ondrej sindelar has now joined his former teacher, the bassoon wizard Sergio Azzolini, to record Zimmermann's version of the double concerto in it's world premiere, supplemented by a solo concerto by Zimmermann (another premiere) and one of Vanhal's three preserved concertos. Noteworthy music that is previously undiscovered in the hands of wonderful soloists and orchestra - that's a real musical feast.
