Master drummer/percussionist Kahil El'Zabar invited special guest, violinist Billy Bang to perform live at Chicago's River East Art Center on December 18, 2004. The concert was a multi-media event with painters, sculptors, and video projection. This is the first recording with new member Yosef Ben Israel. The fit is perfect as Yosef lays down the wicked bass grooves that are the foundation of the group's excursions. Ari Brown brings his tenor sax to the edge of screech without crossing the threshold making his statements adventurous yet grounded.
