Robert Plant and his band the Sensational Space Shifters gave the Glastonbury Festival crowd "one of the most musically diverse sets of the day," says the BBC, including songs from his new album, lullaby and... The Ceaseless Roar. They "concoct a fascinating hybrid of dub, jazz, afrobeat and blues well suited to such an eclectic festival," says the Telegraph, "and an appreciative audience swayed in the setting sun to blissful world groove ... Plant's still got the vocal chops and stadium charisma." The Guardian calls him "hero." Metro says "Plant still very much has the voice and all of the cool." Watch them perform a song off the new album here.
