Jack White: the hardest working man in rock

Loretta Lynn's 'Van Lear Rose'

After dedicating the crossover release "White Blood Cells" to Loretta Lynn, Jack White quickly collaborated with the country star on this 2004 Grammy-winner. White wrote the track "Little Red Shoes," sang a duet with Lynn on "Portland Oregon," and performed musically on the entire effort, to overwhelming critical acclaim. Lynn has yet to release another original full-length.
