The recent news of La Scala commissioning an opera to be based on Al Gore's An Inconvenient Truth from Giorgio Battistelli has raised a few eyebrows (and nasty comments from "low brows" as well).
I can't imagine a less musically-inspiring character than Al Gore as the "hero" of this or any other opera. Yes, his speaking voice is resonant, but it is not at all musical (I would call his voice type a deep monotone). I imagine that Battistelli would be able to do a fine job of giving a sonic picture to the concept of global warming (perhaps even using musical material derived from the data that the Gore power points represented in the film), which takes care of everything he needs to be concerned with except the plot and the characters, who, because it will be an opera, will be expected to sing.
At least Battistelli has a while to figure it out. Maybe by 2011 the threat of global warming will be history. Who knows?
