Robert Plant's Band of Joy reflects his unquenchable thirst for new songs and new sounds. Not satisfied with his stature as one of the great innovators and heroes of pop music, he continues to let his curiosity guide him to unexplored territory. Building on the roots-imbued sound he achieved with Alison Krauss on the wildly successful Raising Sand, Plant's song selection and incomparable vocals make Band of Joy a new triumph.
