***AIDAN BAKER’s anodyne ambiences almost act as aural dream machines on their own. But now Baker has collaborated with actual film makers for his Opus Dei, embodied in this double DVD set (one credited as Aidan Baker and the other to NADJA). Clocking in at nearly 6 hours, this in-home installation is the ultimate video aquarium for the acid-minded. Baker's thrum-scapes lay back and patiently coo mantras something akin to mid-period Nocturnal Emissions or Vidna Obmana, while spectacular visions wend and squirm from the absolutely abstract to hi-def nature photography, all to blissful affect. Some footage oozes out and away, like Cocteau Twins albums come to life, while other footage juxtaposes layers of treated imagery ala Derek Jarman experimental films, or early Cabaret Voltaire Doublevision videos.
