"The term may be slippery, but it's a useful framework for considering how ideas about taste and authenticity have infected writing and thinking about music over the years. And not just in the rock era: All who have sought to separate high from low, art from trash, the folk-authentic from the synthetic-mass-marketed, the bad new from the good old—the folk revivalists in the 1950s, the Dixieland jazz purists in 1940s, the Victorian parlor-song champions who blasted Tin Pan Alley ragtime in the 1910s—were, in their way, arch-rockists. Undoubtedly there were plainchant rockists back in 13th-century France, thumbing their noses at that god-awful polyphony."

Jody Rosen in Slate wonders if today's music critics are missing something when denouncing "rockism."

And Douglas Wolk in the Seattle Weekly offers a narrow definition for the term.
