David Guetta performs at WaMu Theater at 8 p.m. this Saturday.How big a deal is David Guetta? So big that he was able to hire an ex-Pentagon investigator last week to look into the theft and leaking of his new single “Where Them Girls At” featuring Nicki Minaj and Flo Rida. Sure, it sounds melodramatic, but it’s that sort of fierce dedication to his music that has made the French producer and DJ so successful. Still riding the momentum of his 2009 album One Love–last year, he re-released it as One More Love–Guetta has dominated the charts with a slew of hip-hop-laced house-music hits. It is highly unlikely any of the high-profile artists those hits feature–Akon, Kelly Rowland, the Black Eyed Peas–will make an appearance at this weekend’s concert, but Guetta is enough of a star in his own right that he can still pull off a hell of a dance party. So leave your stilettos at home–you’re bound to return home with enough blisters on your poor feet as is.Follow us on Facebook and Twitter.
