If this seriously good series has escaped your attention then rush to the iplayer now. Suzi Klein tells the story of how music and politics were entwined in the twentieth century. The first episode focuses on revolution in Soviet Russia and Weimar Germany: we have some great sequences about Weimar cabaret and avant-garde Soviet music (a symphony for factory sirens), culminating in a chilling sequence about the Horst Wessel song. The second covers Strauss’s seduction by the Nazis, and some equally scary footage on the exhibition of degenerate music in thirties Berlin. The tightrope composers walked in Soviet Russia is also set out. Klein is very knowledgeable and every ten minutes features some footage or incident you’ve never heard before. Essential viewing. Music docs of the year for me, even if you’ll never be able to enjoy Carmine Burana in quite the same way again.
