Birth name: Pierre David Guetta
About him: Guetta had already topped the charts in 12 countries before will.i.am snagged him for production duty on the Peas' unavoidably infectious 2009 party anthem "I Gotta Feeling." Now he's the go-to dance-pop producer – and has helped pave the way for dance music's recent pop takeover.
Artists he's produced for: Black Eyed Peas, Kelly Rowland, Pitbull, Flo Rida
Artists he's remixed: Madonna, Black Eyed Peas, Snoop Dogg, Shakira, Flo Rida
His sound: Squelchy, endorphin-emitting synths. If "ecstasy" were a sound effect, it would be named "Guetta."
Track that best captures his essence: The Black Eyed Peas' "I Gotta Feeling."
On his style: "Is it dance? Is it urban? It's difficult to say," Guetta told Rolling Stone in 2010. "But it's very exciting."
