Gee whiz! I cannot but exclaim so when I read the names of two grand masters of frontier sonic disciplines, Richard Chartier and William Basinski, who already showed how complementary their sonic languages are on "Untitled", which was releases almost ten years ago by Spekk. Chartier's personal declension of minimalism as a collection of entities on the threshold between silence and sound and Basinski's pulchritudinous harmonies in ultra slow motion coalesce again on this highly visionary 45 minutes lasting track, whose title "Aurora Liminalis" and beautiful cover artwork sound like a sort of walk-through for listeners. It could be splitted in two parts: on the first one, there's a sort of gradual ascension, where Basinski and Chartier describe a dawn in minute details, so that listeners could almost feel they managed to expose each single photon of each sun ray as well as the gradual spreading of light by means of a slow fade-in which manages to evoke this daily spectacular natural show and the charming paint of its inanimate and animate onlooker and bystanders. While you could imagine that sunbeams are trying to reach the abyss of oceans, the sonic watershed begins to sneak in just after nine minutes. It slowly taxies and percolates till it becomes clearly distinguishable and sounds hypnotic as if it were the sonic representation of chores, social conventions and any possible epiphany of self-identity, which could divert attention from surrounding happenings, whose sonic comeback sounds tardive as the sun is already withdrawing and dragging the colours from the world. The singed electric buzz on the final part of the descending phase of "Aurora Liminalis" almost evokes the metaphoric smouldering of the night and the soot of the fog, where the bonfires of artificial lights could let you think about the last burning points of an almost completely charred leaf soon thereafter the sun removed its colourful warm mantle. You shouldn't wonder how an ambient record could suggest such a scenery when sonic scenographers are so talented. A proper little masterpiece.
