Acapella

This is the lead single from American R&B/hip-Hop singer Kelis' fifth studio album, FleshTones. It is her first new material since 2006's Kelis Was Here. The track was inspired by Kelis' baby son Knight, whom she gave birth to on July 21, 2009.

The song was helmed by French DJ and dance producer David Guetta, the man behind The Black Eyed Peas' hit, "I Gotta Feeling." This electro techno groover took the New York born singer-songwriter's hip-hop-driven style in a more electronic/dance direction and the track reached #1 on the Billboard Hot Dance Club songs chart.

The song's music video was shot in Los Angeles with the director team of Chris Cottam and Rankin. It features Kelis as the last woman standing on earth who adopts the tribal way of life. She told Rap-Up.com: "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. 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, "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."
