Kelis' new album Flesh Tone hits stores today and has already been tipped as one of 2010's "Best Bets" by Billboard. The David Guetta-produced single "Acapella" is already an international No. 1 hit, while the festive "4th of July (Fireworks)" is a club banger that mixes R&B soulfulness and electro breaks with a rip-roaring wobbly bass riff. Kelis says of the album, "there's a physicality behind it - it's about blood, muscle, heart. I was pregnant when I recorded 75 or 80 percent of this music... And that became a real driving force for me. She also worked with label head will.i.am, Alle, Benny Benassi, Free School, Boys Noize and Burns to achieve her club-ready sound.
