In 2011, John Calvert stated that "timing" is the reason why a grunge revival did not happen; he says that the cultural mood of the late 1980s and early 1990s, which inspired the movement, were no longer present. Seattle songwriter Jeff Stetson states that people from the 2010s who are listening to grunge should learn about the "... context and history of how it all came to be" and "... respect for what a truly amazing thing it was that happened here Seattle, because you probably won't see anything like it again." "Paste" magazine's Michael Danaher states that the grunge "... movement changed the course of rock 'n' roll, bringing ... tales of abuse and depression" and socially conscious issues" into pop culture.
