Solange, the more-credible of the Knowles family, took to the stage on David Letterman’s show last night for a very cool performance of new song ‘Don’t Let Me Down’.

I’ve always been a fan of Solange, right from the early days (remember ‘Feelin You’ ft NORE?), and she’s just grown into the most talented of young artists over the years.

Watch the video of the performance after the jump. ‘Don’t Let Me Down’ is off Solange’s new 7-track EP ‘True’, available now from iTunes.
