Recorded at a concert in London, September 1984, this supersession brings AMM stalwarts Keith Rowe and Eddie Prevost together with saxophonist Evan Parker and bassist Barry Guy for an amazingly diverse and cohesive long improvisation.

"Eddie Prévost is not only a highly articulate percussionist but also a stimulating writer, writing for example his occasional contributions to The Write Place or his examnation and critical reactions to The Ganelin Trio in Wire 7. This CD release from Prévost's own label comes with a thought-provoking essay on alienation strategies in music. He contrasts these methods with the approach of the participants in this concert recording, who "do not seek to 'demonstrate' an alternative form. They are content to perform in a mode which has become the simple and natural means of musical expression."

I supose that this is 'difficult' music, but these exponents inhabit the unfamiliar places of this sound world as if they were the most natural of habitats, which for them they are. This is a hermetic environment in which the four elements interwine, merge, discourse, shape-swop and shift. It may be self-contained but it is not unwelcoming to audiences prepared to give something of themselves, to melt into passages of hushed, eery beauty, to be sucked into vortices of thunderous turbulence or to particpate, albeit vicariously through their responses and imagination, in the creation of unremembered sounds.

The rapport between the musicians and the unconventional noises they produce from their instruments challenge the listeners' powers o fidentifying and distinguishing the voices of the individual players. Enjoyable though this game is it is hardly the most fruitful approach. Details of timbres, component sound relationships, transmutations of constituent parts of the music and, flipping the telescope over, the overal effect of the tapestry matter more than individual credits.

A supersession for sure, music-making of formidable integrity (in all senses of the word) which offers seemingly infinite and inexhaustible prospects."-Barry Witherden, The Wire July 1989
