How come hardly anyone knows about Rush the Canadian rock band?

Answer 1

That may have been true in the 1980s or even the 1990s, when Rush was still considered a cult band by many people. But the band's popularity has grown dramatically, with a new generation of fans embracing their music. You can hear Rush songs in commercials and in the soundtrack of movies; the band now has a star on the Hollywood Walk of Fame, and they were inducted into the Rock and Roll Hall of Fame in 2013. There is also a documentary about them. Thus, it is no longer the case that "hardly anyone knows about " Rush.
