As much as the appeal of an orchestra to many musicians and listeners is the greater scope and size of sound, the small group can score equal points for its sheer intensity and focus. This trio, which is unusual for its combination of instruments and the singular nature of the personalities, is a fine example of the latter. Buckner is one of the great mavericks in contemporary jazz vocal, a man whose wobbling throat vibrations, primal screams and shrieks have distinct orchestral implications, and they are heartily reinforced by his two very wily collaborators. Leandre's deep-toned bowing seems to cushion the harder presto notes of his voice as her agitated fretting needles its softer legatos, while Mitchell's flute is both the ‘flowing stream’ of the title and a kind of sonic drizzle and floating spray, particularly when she pushes towards the sensual, woody density of an Indian bansuri. Having said that, the instruments essentially act as voices in a subversive three-part harmony group where one musician is singing around as well as with the others. The clever distortion and overtones just create the illusion of another vocalist joining the fray. Indeed, Leandre's furtive singing in French adds a smart textural and linguistic layer to an ensemble sound enriched by three very strong characters.
