The voices are wonderful, but the recording is so faulty that only the two tracks from Iolanthe sound at all okay. At first I thought it was my equipment, then realized that the CD was at fault. And I bought one for myself and one for a friend! I adore Gilbert & Sullivan and D'Oyly Carte is the best, but this particular CD shouldn't be offered for sale.
