I had the pleasure of performing this arrangement of Mozart's Overture from The Magic Flute in the Seminole Trombone Quartet in my time at Florida State University. These operatic arrangements offer tremendous technical challenges to brass players because of the imitation of the string parts. Here, the Budapest Trombone Quartet gives a stunning live performance of this overture.
Another great example of an overture arranged for brass comes from Verdi. This performance of his Overture to "Nabucco" is performed by the Gomolan Brass Quintet.
Finally, on a more comical note, the Mnozil Brass with their own opera medley. The Mnozil brass, a European brass ensemble that transcends the boundary between musicians and actors, is most known for their incredible brass playing and comical wit.
