Certain instruments tended to distort, the brasses in particular accruing a cavernous resonance.

While much of Mr. Branca's work has used high volume to produce hallucinatory sounds, "Movement Within" created cavernous resonances without bedlam.

While it's not exactly playful, and often uses the same dark minor or modal harmonies as industrial rock, techno has a lighter touch; instead of cavernous resonances, its productions have the ambiance of an acoustic-ceilinged, carpeted office or a shopping mall.
