A growing list of bands unpopular with critics, but genre-defining nevertheless, is impatiently awaiting their admittance into the Rock and Roll Hall of Fame.
As the years progress, the process of getting into Rock and Roll Hall of Fame is beginning to look a lot like the process of earning a letter for a high school letter jacket: The superstars (Bruce Springsteen, Prince, Aerosmith) are awarded just for showing up, as are the academic overachievers who are still social enough to get a seat on student council (U2, The Police, Talking Heads). However, the nerds who create the science fiction clubs and painstakingly put together the yearbook (Rush, Genesis, Yes, Kraftwerk) face a much steeper battle for recognition. And while you can't really letter in smoking, there's no way to recognize the smokers and the class-skippers (Slayer, The Replacements), those folks who are just as essential as the jocks and student council presidents in defining the experience that is Rock and Roll High School.
Fans, and even non-KISS fans, have been screaming to let KISS into the Hall of Fame. But now that their work is done, people have started to raise a ruckus about why progressive rock has not been represented. As for speed metal fans, a Metallica nod won't be enough to keep people from demanding a Slayer induction as well.
The nomination of Genesis is a decent start for progressive rock, but King Crimson, Yes, and Rush are still patiently waiting for nomination. One problem for progressive rock is that, in general, it's not a genre adored by rock critics. But regardless of whether you think 2112 or Relayer is a masterpiece, progressive rock's most notable characteristics (the odd time signature shifts, full albums broken into "acts" or "suites") are everywhere in rock. If a song by a rock band exceeds eight minutes, chances are high that there's going to be a Yes comparison. Even a band as critically adored as the Decemberists has garnered plenty of prog rock comparisons.
