The 10th annual 'Roo is underway. Here are Randy Cremean's great pics of some of the notable sets from the first two days of this year's fest in beautiful, boiling Manchester, TN. Featuring Sleigh Bells, Lil Wayne, Twin Shadow, Big Boi, Wavves and Best Coast (aww), Karen Elson and Jack White (hmm), Jim James' hair, and more.
