Query: Thank You, Joel and Ethan

The Coen brothers with their splendid (and hilarious) movie "O Brother, Where Art Thou?" have created a resurgence in the popularity of old timey/bluegrass music which is unprecedented. The album went Top 10 on the pop charts. It was the CMA's Album of the Year. It has focused the spotlight on artists like Ralph Stanley. For that alone, Joel and Ethan Coen have earned my eternal gratitude. Several of my friends have told me how much they've loved this album. I've encouraged them to consider artists like the Stanley Brothers, the Carter Family, the Dixie Hummingbirds, Robert Johnson or Mississippi John Hurt, among others. But even if they stop with this collection, this is powerful music from veterans like the Fairfield Four and Ralph Stanley along with artists like Norman Blake, Emmylou Harris and Alison Kraus. HIGHLY RECOMMENDED
