I adore these. First we had them, then we could not get them any longer, now they are once again happily sitting on our shelves awaiting a home. These very well might be one of the best value $20 items we sell. Each book contains the full opera on 2 CDs. The book itself is rich with information, containing the complete libretto with annotations. Perfect for all ages, novice to seasoned opera lover too. We listened to them the entire day at the shop on Wednesday and it just put us all in good spirits.
