Anytime the Art Ensemble of Chicago saxophonist records, the smart move is to clear your schedule. This always intense and often quietly meditative album ranks among his stronger recent releases -- due in part to the rumbling percussion (and occasional pianism) of young gun Tyshawn Sorey. As with some Art Ensemble efforts, things start slowly (with bell-shakings). But there's heated stuff, too, like duets "The Way Home" and "A Game of Catch." And when trumpeter Hugh Ragin joins the fracas on "Scrunch," the tumult increases. Albums that manage power even in quiet moments are rare. Here is one.
