The earthy tone of Malaby’s tenor fits snuggly with pianist Stacken’s cunning freebop. With drummer Tom Rainey guiding things while enhancing the textural quotient, Stacken’s tunes take on a mischievous nature – very inviting stuff. The second half of this double bill finds the saxophonist sailing over an unholy alliance of shadowy strings and a fat brass bottom. Call it a porto-orchestra.
