As for spectacle - slightly comic spectacle, admittedly - he never, ever disappointed. Is there a link between Alagna's somewhat constrained dramatic skills and the Las Vegas rigours of his stance, body leaning forward, right hand pinned to chest or lapel, left hand stretched toward an invisible microphone or a sob? Maybe a doctor can advise.
And this from a guy who actually really liked the recital (complete with "a limp Desdemona impersonated by Alagna's jacket").
