This music can't stay underground. It's coming out with a fresh voice, a distinct mix of sounds, and an established, growing audience. It's got all the beats, cuts, and rhymes you could ask of rap, but it's got more than that. AMB have taken west coast gangsta rhythms, mixed them with heavy metal attitude, channelled them into R&B harmonies, and added a range of experiences from their work underground. It comes together with a fluid smoothness unique to itself. "Blood in" is what you thought you knew, and "Blood out" will be the brand new you. AMB are the new sound of the Underground, and they'll be sticking around.
