An ominous build of "wind" noises and orchestral instruments. Slowly rises in tension and density from low bowed acoustic guitar, processed percussion, and climbing, atmospheric strings. From this dark background, a Yali Tambur (African hand drum) creates a driving feel (@:08), while climbing strings and processed choir/vocals/blown aluminum pipes evince a growing, swirling wind noise that rises in pitch and tenor to a final hit @:29. The second half starts the build again, this time slightly sparer mix-wise. A break @:47 leads back to the main building theme @:52. Good for tornados, hurricanes, climate change or building tension.
