Sound Hierarchy is an album by the Brazilian jazz saxophonist Ivo Perelman, recorded in 1996 and released on the Music & Arts label.

He leads a quartet with pianist Marilyn Crispell, drummer Gerry Hemingway and bassist William Parker.

In his review for AllMusic, Alex Henderson states: "Short of Charles Gayle, you won't find any 1990s avant-garde jazz that is more incendiary, ferocious and violent than Sound Hierarchy.

"[1] The Penguin Guide to Jazz notes that "Crispell is too strong a personality to settle for the kind of subsidiary role that Perelman needs, and Hemingway's rhythms are too bracingly inventive - they offer Perelman a distraction rather than fed lines.
