Now Dido is back, releasing her fourth studio album in March, and leading off with this vigorous track featuring current rap favorite, Kendrick Lamar, who like Eminem is a member of Dr. Dre's Aftermath label. Produced by Dido and her brother Rollo Armstrong with Jeff Bhasker, "Let Us Move On" has the fractured gloss of a Kanye West track and a message of realistic hope that fits with Dido's previous music. Lamar revs the song's engine with a rhyme that starts out quietly and rises like a temperature. "Got these burdens under my wings, but I'm still free," he admits, before taking his final flight. Then Dido comes back to help us ride out the journey.
