To hear a classical singer every bit as immersed in his style of singing, listen to Luciano Pavarotti. Early on he became known as the "King of the high C's" because he had such gorgeous ones. His voice is extremely beautiful, no doubt, but it is his style that interests us. He uses the tools with complete mastery and self-confidence.
He stays with his strengths. Throughout his career he has emphasized Italian repertoire, mainly Verdi, Puccini and the other verismo composers, exactly the repertoire that would show off his particular style of singing.
My favorite recording of him is Puccini's Manon Lescaut with Mirella Freni, also from Modena.
