Danish-German composer Dietrich Buxtehude has an extensive output of vocal music in addition to his far better known canon of organ music. The vocal music is more obscure in that it is such a mixed bag. The oratorios he wrote have gone lost, many pieces relate directly to the organ music in a way that is difficult to divine now and some of the sacred concertos he composed are less than compelling, written for afternoon lunch concerts and not meant as "serious" music.
