Ellington and an iPhone app

InstaCRT is an iPhone app that projects a photograph onto a CRT (cathode ray tube) in Sweden and returns a photograph of the resulting image. That’s nice.

What interests me more though is the music in the app’s demo video. “What is that music?” I asked myself. And a voice replied, “It’s a slowed-down loop of the first four bars of ‘The Brown-Skin Gal in the Calico Gown,’ by Duke Ellington and Paul Francis Webster.” Here is the 1941 Ellington recording, with Herb Jeffries singing.
