In Camera Open Air CD Robot Records Available through the Helen Scarsdale Agency: $13.00      Open Air is musical moonshine; it was recorded live and out doors, by the light of the moon, presumably for a small group of friends. The entirety of the album consists of many of the elements expected from this duo: slow, low-end drones; a counterpoint of high, slightly metallic rustlings; and just a smattering of odd percussive sounds or otherwise out-of-place errata. Just a few elements and a bit patience yields an undeniably gorgeous record that scares up equal parts paranoia and reverence. When the sounds are worked up into an intensity of any sort, Heemann and Van Luijk smartly provide a lull and introduce new or slightly altered elements in order to keep the mix dynamic. There's nothing dull about their process nor the resulting music, but there's a level of predictability to this group's music that's difficult to ignore. Fans of Mirror and other like-minded groups may be able to grasp the scope of this album within their imagination and thus plot out its course before even hearing the first minute.       The album begins with a hushed drone, a sudden thud, and with the sounds of laughter or conversation evident in the background. This is the only indication that the album has any live element to it whatsoever and it lasts only seconds. Over two long tracks, In Camera builds up rumbling soundscapes and understated howls that move gently back and forth. The second song features several sections where the instrumentation employed to make all this sound is almost identifiable; I hear a Japanese flute and perhaps a pump organ winding into each other seamlessly, perhaps a detuned guitar string being teased slowly, too. Yet, the music remains alien and disconnected from the real world. By the time the record has ended Open Air, like the best drone records, has transported you somewhere else and induced amnesia. The sound stops and then all the sound in the room returns to claim dominance.
