It is only in the last few years, largely as a result of the pioneering performances of the Simon Mayr Chorus and Ensemble conducted by Franz Hauk, that Mayr has come to be valued as one of the most significant composers of operatic and sacred music of his time. Il sagrifizio di Jefte (The Sacrifice of Jephtha), first performed in 1795, is a dramatic oratorio with a wealth of variety in both the vocal and instrumental writing, which foreshadows the operas to come.
