I have to take issue with Stacy’s dissing of folk music. Just because most of its prominent musicians were liberals, even socialists, it doesn’t take away from the quality of their work. When it comes to art, I think you have to set aside politics.
Besides, as leftist folk musicians go, Woody Guthrie knew how to stick it to the Nazis:
There was a man across the ocean, I guess you knew him well,
His name was Adolf Hitler, goddam his soul to hell;
We kicked him in the panzers and put him on the run,
And that was about the biggest thing that man has ever done.
