This was produced in Reason 10. The key can be thought of as A Phrygian Dominant (D Harmonic minor). The intro section is three long measures of 7/4. When the tribal flute hits, the bass continues to play polymetricly in 7/4 while the rest of the song stays in 8.
After the flute section, the song remains in 4/4 till the end.
The plucking reversey delayed thing at the beginning is a clean guitar recorded directly into Reason and placed into a Dr. Octo Rex drum sampler. I reversed specific slices of the audio, pitched the whole thing up an octave, and applied a liberal amount of delay.
