Foxygen made their late-night TV debut last night on The Late Show With David Letterman, and it looks as if they made a famous new fan when all was said and done. The band played the …And Star Power cut “How Can You Really” and pulled out all the stops. Bringing in a trio of backing singers to augment their sound, the band gave an electrifying performance, with singer Sam France channeling Mick Jagger and James Brown for his dance moves. Even that noted curmudgeon Letterman was impressed. You can watch Foxygen’s full performance below:
