While their straight-up rapping skills are indisputable, it's the group's quirky arrangements, production style, and preference for live tracks instead of pre-programmed ones that sets them apart from the pack. <p>Throughout BRIDGING THE GAP, the trio makes it clear that they're on a mission to take hip-hop to a smarter, more sophisticated place. This is accomplished almost as much by what they don't do as by what they do. They spend a lot of time talking about unification and other high-minded ideals, and distancing themselves from any notions of violence. They also take care to collaborate with artists they consider like-minded, including De La Soul, Wyclef, and Macy Gray. BRIDGING THE GAP's mix of funk, rap, pop, and soul is a strong brew when combined with the Black Eyed Peas' often-heady lyrical sentiments.
