For myself, it originated from 'My Philosophy,' the greatest set of vibrations I've ever heard. Now, the roots of the production, to my knowledge, goes back to Critical Beatdown. They did experimental and influential things, sonically, with that record. And you can also factor in Pete Rock (and Marley) for molding that organic jazz fusion over homely bass and hard drums (knocks). The wind echos and low hums definitely come from his production.
