It is clear that within the quartet there is a very profound and intuitive artistic debate which makes for a particularly fine tuning. This is a fundamental characteristic of Grapeshade, generating a great openness and alertness to every one of the fellow performers throughout the instant composition. The resulting permeability to every instant, as well as to the the unfolding of the event as a whole, gives rise to a great clarity, present even in dynamic and turbulent passages.
