I wrote about this somewhat hard-to-believe meeting between Duke Ellington and Conny Plank in 1970 for The Economist's Prospero blog. I spoke with Plank's son, Duke's son and Michael Rother for the piece. My conversation with Rother was longer than necessary and revealed a lot about the relationship between Plank and Krautrock musicians in general. When I have time, I'll edit that and post it here. In the meantime, you can find the piece on the Economist.com.
