Following in The Chemical Brothers' footsteps means choosing which of their paths to pursue: breakbeat rave-ups, psychedelic trickery or ingeniously twisted pop. Justice's headbanging "Waters of Nazareth" proudly flies big beat's flag, while Crookers & Kid Cudi's "Embrace the Martian" recalls the duo's hip-house with Q-Tip, and the bros' '60s fascinations swirl through UNKLE's "Restless".
