Query: Susannah Waters!

I must add one thing to the other five reviewers' praises: Susannah Waters - who has now gone on to a successful writing and directing career and who you may have never even heard of as a singer - here sings the most limpid and nimble lines you can imagine in the Act 3 masque with the Cold Genius. Her lyrical lines are melting and warm, yet well within the parameters of taste of today's baroque specialists; and her ornamentation is stunning and graceful and fleet. I wish more baroque singers combined these two qualities so well. I don't know why she quit singing, but this recording makes me sorry she did. Nevertheless, I greatly admire someone with this much talent who moves on to do other things with equal panache.
