A big voice ,not convincing in his phrasing,he is supposed to be desperate,he is going to be killed and jet no emotion in his voice in the final minutes of his life just like Domingo (ONE OF MY FAVOURITE)no light / dark voice expression ,i love you or i hate you is sung with the same voice quality,after a while this is boring ,lucky those that don't understand the Italian language ,Calleja has the potential to improve and do better a voice teacher can straighten him out Grazie Signor Calleja
