"Pat Metheny’s noisy Zero Tolerance For Silence is one of the most challenging albums of the 1990s.
I may not be the only person who continues to listen to the abrasive project for pleasure. Headrush, the debut album by Kansas City’s Hmph!, is a similarly corrosive guitar-based freakout.
Hmph! may well be a math-rock band rather than a jazz group. Whatever label is applied to the approach, it’s clear that Hmph and the like-minded Jorge Arana Trio are two of the most interesting improvisatory instrumental ensembles in Kansas City." - Plasticsax.blogspot.com
