I get the "Don't give labels" pitch, that everyone from Duke to Miles has stated. On the other hand, for purposes such as choosing a style top back a particular groove, nomenclature is inevitable.

"Modern Jazz" was a term coined before most of us were born, has been applied to a certain era and genre, and does not represent a "sliding" timescale. "Funk/Fusion" will be immediately understood to represent Spyro Gyra, Hancock etc. As these styles are now more than two decades old, how is referring to them as "modern" any more accurate than applying it to Bird and Diz?
