Stimulating sounds here from this heavyweight avant duo, a parity of esteem in the saxophone and flute playing of the Canadian Anna Webber and US pianist Matt Mitchell and an in-the-moment energy and inventiveness at every turn no matter how abstract or impenetrable the course of the improvising lines become. Webber has also released a larger group album on the Intakt label recently entitled Shimmer Wince. Dense and quite often intense but certainly not arid or clinical the main piece here is the lengthy 'Re-aeration' running at nearly half an hour but there are ''moments'' to be found on each of the five pieces. While not the same period or exact idiom at all I kept thinking that the rapport the two display shares something with that of Steve Lacy's work with Cecil Taylor - a similar meeting of minds from a good deal more than half a century ago.
