Shabazz Palaces and THEESatisfaction form the basis for a family of Northwest artists that includes the hiphop producer OCnotes and producer/rock musician Erik Blood. Imagining a cooler family of like-minded headz is nearly impossible. I can honestly say that Palaces and Satisfaction have reinvented a large part of hiphop and established a new direction for black politics. The Afrocentrism we hear in their music has no center and is not closed but completely open to the world of ideas and feelings. (Neptune Theater, 1303 NE 45th St,, 9 pm, $21.50 adv/$25 DOS, all ages)
