Belgian singer-songwriter Selah Sue takes her cues from Erykah Badu and M.I.A. What else? She's duetted with Cee Lo and sung a song for a Häagen-Dazs commercial that features Bradley Cooper. She made a name for herself internationally with the songs 'Raggamuffin' and 'This World', and will likely sing from her self-titled debut album and her 2011 album 'Rarites' tonight at the Olympia.
