Dido and Aeneas
Radio 3's Discovering Music series has some excellent notes on Purcell's Dido and Aeneas, as well as a video analysis of Dido's Lament. This will provide you with invaluable information and analysis so please click here for more details.
Purcell was also one of Radio 3's 2009 Composers of the Year and I have downloaded some very interesting broadcasts about the composer, which I will send to you or put on CD for you.
Here is the link to the Purcell handout.
