Toma Gouband plays percussions with singing stones, foliage, drums, pin apple, and develops rythms based on proportions, crossing speeds, colors.

"One doesn't even need to 'enter' into the music of Toma Gouband: our ears (and eyes, if we have the pleasure of seeing him at work) are invited, by the spectacular and extraordinary organisation of colors and timbres that make up his dreaming inventive universe. Pieces of flint, natural skins covering a horizontal bass drum, which has scattered upon it tiny bells or blocks of wood, branches and twigs... pebbles rolled on the ground, inverted cymbals collcting thus all sorts of natural resonators... The high-hat cymbals have been replaced by...they've also been replaced by stones! Animated by an interior pulsation made from the superimposition of mysterious cycles, like so many clocks telling life's time in polyrythms that collide and cross over each other, the music of Toma Gouband transcends the idea of an imaginary territory, for it invites us to approach it as we would a social rite or even a ceremony of love. A weaving of the tissues of sound, with wisdom, sio that we feel them as universal, as though they come or to become, for which the visual metaphor could be those traditionel Kuba cloths from Upper Zaire that made of fabrics sewn one on top of the other, to which are added motifs according to an organisation that is rigorous but seems to be governed by rules that have been transmitted only to the initiates who create them. Thus, this is a music initited by the history of the world, unique, free of the constrains imposed by convention and which responds only to its own interior strenght: a summit of the musical art."-Benoît Delbecq
