Karlīna Īvāne played my "Four Pieces from Doktor Faustus" a couple of days ago, and put the performance on YouTube. I am happy to share it here. If you know the Thomas Mann novel, you should recognize the references. If you haven't read the novel, I recommend reading it!
The first movement is based (loosly) on the song "Oh How Lovely is the Evening," which is discussed at length as one of the pieces that Leverhuhn and the narrator sang together. The second movement is based on the Hetaere esmeralda row and incorporates the Tristan chord. The third movement represents the encounter with whatever it is that the narrator (who is a viola d'amore player), says that Leverkuhn (the composer and main character) encounters, be it a daemon or a hallucination of one, and the last movement is a "portrait" the little boy called Echo.
