Opera Holland Park do the double

Zanetto / Gianni Schicchi - Opera Holland Park, 22 June 2012 (opening night)

Kudos to Opera Holland Park for continuing, year after year, to revive long-forgotten Italian operas. But in the case of Mascagni's one act Zanetto, I wonder if it was worth the effort.  The ruminative non-plot and politely anonymous music make its 40 minutes pass like four hours.
