Mac Miller is the latest artist to step into NPR's office and play a Tiny Desk Concert. The live set can be seen above and coincides with the release of Miller's lates album Swimming last week. Miller was joined by Thundercat on bass for his NPR set, which consisted of new songs “Small Worlds,” “What’s the Use?” and “2009.” Mac Miller will tour with Thundercat and J.I.D. later this year. The run of shows will kick off in San Francisco on October 27 and will conclude on December 10 in Vancouver.
