A reviewer in FanFare magazine (JD) gave this a strong recommendation, and since his thoughts and mine frequently are on the same wavelength I made the purchase. First, I would never have thought this music could originate from von Suppe. We all know his operetta works to some degree, but this is a far more sophisticated orchestral and choral piece and amazing to hear. The first portion I find the best and certainly the least like von Suppe. This is the Requiem aeternam. The following sections include the Dies irae; Tuba mirum; Rex tremendae; Recordare; Confutatis; Lacrimosa; Domine Jesu; Hostias; Sanctus; Benedictus; Agnus Dei; and finally the Libera me. I am not Catholic and cannot state with any certainty that this is the standard church full Reqiuem, but it is longer and more inclusive than most other Requiems. I found the composing of the sections other than the Requiem aeternam to be less than intense, less involving and more pedestrian sounding. Certainly this is why the von Suppe Requiem has not gained the attention that others have. JD in FanFare magazine said "I might dare to go even further and declare that Suppe's Requiem, as a Requiem, is superior to Verdi's." In my opinion this is just not true and von Suppe comes nowhere near the musicality, intensity and beauty of the Verdi. But for a real switch from operetta to this is something for von Suppe. If you are intellectually curious you may want this in your collection.
