The Indian Queen, English National Opera
    
      
  
  
  
A colourful but eccentric production veers between beauty and incomprehensibility
When Purcell died at just 36, he left The Indian Queen unfinished, which only adds to the usual problems of staging his "semi-operas" – plays with musical interludes which don’t really accord with modern operatic tastes, despite the ravishing beauty of the music itself.
