After decades of underground toil in Paris' club scene, DJ/producer David Guetta broke through to the mainstream on his fourth album, One Love. Akon helps turn the club-ready "Sexy Bitch" into a soaring ode to midnight magnetism, while Estelle lends her powerhouse pipes to the uplifting title track. A collab with Chris Willis calls back to Guetta’s house roots, but the highlight is “When Love Takes Over"—a pristine piano-house anthem with a classic diva workout by Kelly Rowland.
