This disc has a large number of small snippets, and several more extended bands, of very fine singers of the past. For the most part, these selections should be considered as supplementary material - giving an interesting visual representation of the great singers and their performance practices of the past 100 years - rather than as exciting performances, which you would watch frequently for their entertainment value. Needless to say, the quality of the audio and video varies widely from the crude early selections, through the fuzzy cinemas of the 1930's to the relatively acceptable quality of the later singers in the 1960's.
