In case you were wondering, the plot will combine The Tempest and A Midsummer Night's Dream. You can read a synopsis here (PDF). It sounds a little complicated?
I spent some time on the YouTubes and put together these playlists of the originals. The first contains the music of Act 1 and the second Act 2, in the order they will appear. (Remember that in the pasticcio they will be contrafacted, that is given new texts.) I wasn't able to find everything but did locate most of it. Some of the videos are longer excerpts of which the pasticcio will use only a part. A few of the interpretations here aren't ideal, but many are outstanding, reminding us how far Baroque performance has come in the last decade. (Keep an eye out for our favorite Simone Kermes, who brings her best dance moves to Vivaldi's "Dopo un' orrida procella." Sadly, her Met debut is yet to be announced.)
