80 years ago Washington state was forever changed by the Grand Coulee Dam. The Dam still provides tons of hydropower today, and created a reservoir for farmers to divert and use as the breadbasket of the state today. When it was finally completed in January of 1943, US Government officials enlisted folk music legend Woody Guthrie to write a series of 26 songs about the dam. It’s a quirky moment in US and music’s history – but it produced instant classics that many will recognize, like “Roll on Columbia.”
