Jim James will probably never be mistaken for a Wall Street banker. Sporting a woodsy beard and long mane of curly hair, the My Morning Jacket singer-guitarist looks like his band sounds. At least he did at the onset. Emerging at the dawn of the 21st Century amid a period devoid of music featuring driving guitars and golden harmonies, the Kentucky-based group embraced its heritage with open arms. Soaked in reverb and steeped in ragged country, its early songs spoke with a Southern accent that gave the band a distinct identity.
