This compilation is yet another sentimental favorite from 2009, a great introduction to the "new" wave of dub techno pioneers post BC/DC/ES, a sound still looking for expansion.
Out of print and overpriced on the resale market it's here for your pleasure.
P.S. Notice it's not terrestrial, it's terrestial (which I of course noticed too late as I type this).
And, on an aside, check this video out from Monoaxial. It's posted here because he's on the Area 51 label (from which the comp posted here comes) but also because it's a pretty cool twist on the introductory scene from Pina. All the world's a remix.
