Here’s what Schmwimmer has to say about the performance:
“I fell in love with this strange and beautiful song by Erich Wolfgang Korngold from his Drei Gesänge Op.18 – 1 called “In meine innige Nacht”. Some of you may know Korngold from his great soundtracks from the 1930’s and 40’s. This piece, composed in 1924, reminds me a little of Messiaen… pre-Messiaen. In concert at Carleton College in Northfield, MN 5/8/15.”
Schwimmer pre-recorded the piano part himself. The custom theremin was created by Charlie Hobbs.
