Picking up the tribal theme, Kelis says the video directed by Rankin and Chris Cottam is not 'fashion-oriented at all.'

"It has a really strong, universal, tribal vibe to it. When I say that, I mean it's no particular tribe; it's a little bit of everything," added the alternative singer. "It's like if the world were to end and there was one woman standing, what would it be like?"

"It's not fashion-oriented at all. Actually, it's the complete opposite," she continued her explanation. "I think everything is over-fashioned up that it just becomes uninteresting, and when every artist has access to every designer and vice versa, it's no longer exciting or fun."

An up-beat jam, "Acapella" is produced by acclaimed DJ David Guetta and set to be included in Kelis' "Flesh Tone" which is due in June.
