No I dont have it. I'll have to check it out! thanks for the heads up!
Well, I can actually answer my own question: in the US, anyway, this record is licensed to David Byrne's label, Luaka Bop, which has a Bandcamp store. So last week, on Bandcamp Friday, I added this to my cart, and it came today.
It's pretty fascinating, in concept as much as in execution, maybe more so. The music was actually recorded outdoors, in Joshua Tree National Park, and the surround mix incorporates environmental reverb of the band's amplified sound, bird calls, and "the undulating sound of wind rushing between rock formations and nearby bushes." (Talk about "ambient" music!) They used mics placed at different distances from the speakers, a parabolic "directional" mic moving around the nearby space, and on one track, a flanger. Some of it is cool and organic, some of it a little forced and gimmicky. The music overall is proggy in an early Pink Floyd way, but has lots in common with other, more contemporary ambient/electronic stuff, too. Once in a while it recalls a Yo La Tengo jam. The 5.1 mix (by Joel Rubel and Jack Sugden--names I've not seen elsewhere) is Dolby Digital, and it sometimes has a certain "thin," slightly harsh quality you can get with DD. Glad I bought it, though. I actually want to see what my AVR's Dolby Surround upmixer can do with the stereo mix.
