Los Lobos started out playing weddings in East Los Angeles, a career phase that culminated with a hit cover of "La Bamba." In the decade since, they've been making music for the postnuptial stragglers and burrowing into the subconscious. Teamed once again with sonic chemists Mitchell Froom and Tchad Blake, the quintet continues to expand the acid-tweaked atmosphere of its 1992 masterpiece, Kiko. Conventionally structured songs were at the core of Kiko's experiments, but those tunes are becoming increasingly hard to find as the Lobos spin off projects and solo releases multiply (Latin Playboys, David Hidalgo's Houndog, Cesar Rosas' Soul Disguise). Now the lyrics are more allusive and open-ended ("How come the days do what they do?" Hidalgo mutters on the title song), and the dance floor has never seemed a more subversive place: the Colombian shuffle of "Cumbia Raza," the New Orleans stagger of "Oh, Yeah," the queasy swamp rock of "Viking." Rock's most metaphysical party band strikes again.

“My President”

Young Jeezy teams up with Nas on this track, in which he compare his own success with the idea of an African-American winning the Democratic Party's nomination in the 2008 presidential election. "When I pulled up in my car, that s--- was unbelievable to people in my neighborhood because they were like, 'We grew up with him. How the hell did he accomplish this?'" he told Rolling Stone. "I feel like it was the same way with Obama. I grew up all this time, but I've never seen a black man this close to running this country."
