The only category that even remotely fits for Tortoise is calling them an Indie Rock band. Beyond that, the definitions become murky as Tortoise was very experimental in nature utilizing anything and everything from Krautrock, Dub and Jazz to make albums that were not found on the traditional Rock or even Independent scene. The critics do love them and they found a niche fan base, but this has not proven to be the formula for a Rock and Roll Hall of Fame induction.
To this day, many critics lists and personal lists still rate The Notorious B.I.G. as the best rapper who ever lived. He was called the savior of East Coast Rap and his storytelling ability had few equals. He didn’t romanticize the Gangster life but rapped it in a gritty realistic way. His rapping style also did not seem forced and arguably nobody ever made rapping seem so natural.
Trying to figure out just who started the EMO genre is proving a bit difficult. Sunny Day Real Estate has been given credit by some for that origin, as their debut album took the Post Grunge and brought melodic sounds to it. The band did not last long, but they have been pointed out by many current EMO bands as a group that influenced them. Although Sunny Day Real Estate seemingly meets the influence criteria, but we are guessing that the Hall will look for an EMO band with commercial success to put in instead.
