Query: Outstanding Obscurity

This is one of the so-called post reform Pacini operas (along with Medea & Sapho also available on recordings). The remarkable thing about his post reform operas is the role played by the orchestra. Instead of being backround to the singers the orchestra becomes another voice. Listen to the big bravura duet finale to the first act. It becomes almost a trio with the orchestra becoming a third voice. The outragous, bombastic & altogether wonderful second act finale is one of the greatest in all of opera, not least because of the wonderful part played by the orchestra. I beleive that this new, expanded role for the orchestra that Pacini developed had a profound effect on both Verdi & Wagner. This, and the other post reform Pacini operas are wrongfully neglected masterpieces. Don 't miss them.
