Arguably, the best show- and the most surprising, was from the Dallas-born Erykah Badu. I have always been sort of a fan but after her show I am now full-fledged. Her voice alone is enough to give you chills... She seemed like a Queen, even pregnant and wearing a t-shirt and sweatpants. A true artist.
Below are two great tracks. I'll give you one guess what 'Soldier' is about.
