Willie Nelson's annual Fourth of July picnic is a far cry today from its outlaw roots. Once a communal country-hippie party in central Texas, today it's a slick corporate affair that takes place at the state-of-the-art Circuit of the Americas racetrack outside Austin. Yet, as the 44th installment of the picnic unfurled on the country's most patriotic holiday, it felt refreshingly in touch with those roots. Nelson, never one to shy away from an opportunity to jam, rolled out plenty of old friends and a number of his family members as he celebrated America's birthday like only he knows how, fireworks show and all. With 17 acts playing over 12 hours on two stages, these were the 10 best things we saw.
