Corelli was the leading tenor of his generation and then just stopped singing a year before he was to appear in Otello. He made a lot of complete opera recordings for Decca and EMI, which shouldn't be hard to find from the used dealers--Aida, Turandot, Carmen, Trovatore, Tosca, Turandot,and Norma are the ones which come immediately to mind. He had an astounding, huge, beautiful voice, but wasn't the most sensitive interpreter--even for an Italian tenor.
