Long considered one of the most talented groups in hip-hop, The Roots [ tickets ] have always been an anomaly in the genre. They play all their own instruments--instead of a DJ they rely on Rahzel's human beat box, instead of a drum machine they turn to ?uestlove's taut, jazzy drumming. And instead of braggadocio, The Roots prefer self-awareness.

Also unique to this Philadelphia group is its dependence on a hook-filled refrain. After all, most hip-hop is propelled by a powerful MC, and as cool as Black Thought and his choppy monotone flow are, the rapper is more likely to employ grace than gusto. So, "The Tipping Point," while no hip-hop classic, sees The Roots comfortable in the niche they've carved out. Both "I Don't Care" and "Don't Say Nuthin'" feature memorable hooks with no real distinguishing moments beyond. At least "Don't Say Nuthin'" is musically unique with its electronica-inspired background blips.

But The Roots can still conjure up some addictive grooves. Check out the non-stop hustle of "Boom!," a song tough enough for 50 Cent's next album. The same can be said for "Duck Down!" with its bouncing kick drum and undeniable chorus. "The Tipping Point" sees The Roots trying a little bit of everything, willing to fall or fly from track to track. And they do.
