VIDEO! Watch Solange Knowles perform Sandcastle Disco on David Letterman. LALATE broke Sandcastle Disco first early, early this summer, calling it one of the best songs of the summer.

Back then, no one was really talking too much about Solange except LALATE and few of our fav sites.Since then, Solange’s media blitz … hasn’t been much of a blitz. Until now!

Great ready! Solange is amazing. Her voice incredible. These Neptunes songs are great. LALATE is such of fan of Solange’s sound. Her upcoming television appearances are The Today Show (August 26th), MTV’s TRL (August 26th), The Early Show (August 28th), Fashion Rocks (September 9th), and Jimmy Kimmel Live (September 10th).
