There’s more mayhem, hydraulics, and Paul Giamatti in the new Straight Outta Compton trailer. And there’s also a one-minute intro from none other than Dr. Dre and Ice Cube, who preface the clip by discussing how they used their music to send an empowering message from one of the most dangerous cities in the country. “Our music was like our weapon,” Cube says. “What a lot of people don’t realize about N.W.A. is it’s nonviolent protest.” The movie, about the hip-hop group’s controversial rise to fame, comes out August 14.
