Rush, a Canadian rock band with a lengthy career that began as hard rock/blues rockers in 1968. Their music became more complex over the years and their lyrics often referenced philosophy, fantasy and science fiction. They also experimented with progressive rock and heavy metal for a time before returning to blues rock for good in the early 90s. Rush has sold over 40 million albums worldwide. They were inducted into the Canadian Music Hall of Fame in 1994 and the Rock and Roll Hall of Fame in 2013.
