This film does very much what it says on the tin: if you want to watch a concert featuring acclaimed tenor Jonas Kaufmann sing selections from Puccini, then this is for you. On the stage of La Scala, Milan, in 2015, Kaufmann reduces his audience to ecstatic husks as he goes through the repertoire. As a film, though, this is strictly bog-standard stuff: Classical Concert 101. It’s also prefaced with a tell-me-why-you-are-so-great type of interview with Kaufmann, which seems to go on for an inordinate length; not a great way to begin.
