We've been struggling with this one for a bit. The available audio sample is very short, but the section of music it contains does seem to be distinct to my ear. We are more interested in knowing what piece of music this sample is from rather than an exact recording. It seems to be derived from a piece of music that features a solo operatic singer with a men's choir - I'm certain the original key of the recording is one of these three pitches heard in the audio example below. The recording this piece of audio was derived from will have been in circulation by 1989 at the latest.
My description is certainly a little vague, but the melody the singer is performing does sound highly distinctive to my ear, I'm hoping this may stick out to someone better versed in opera than myself. Thank you!
