Les Troyens
Glossop made a number of recordings. These include "Macbeth" with Rita Hunter in the 1960s, "Billy Budd" under the composer, and the part of Choroebus in Berlioz's "Les Troyens" under Colin Davis. The 1964 performance of "Pagliacci" at Salzburg was filmed, as was the 1970 performance of "Otello".
