Roughly 40 years into their career, a weird thing happened to Rush: they became cool. After decades of being ridiculed as sci-fi-fixated nerds making impenetrable prog rock for geeks everywhere, they finally found themselves hailed as one of the greatest bands in history. Everyone from Dave Grohl and members of Rage Against The Machine to Robert Downey Jr and the creators of South Park outed themselves as fans, while Rush themselves were deservedly - if belatedly - inducted into the Rock And Roll Hall Of Fame in 2013. Of course, if you're reading this, you don't need some Hollywood A-lister or faceless panel of cultural gatekeepers to tell you how brilliant the Canadian trio are. You've spent a lifetime immersing yourself in the records they made, from their Led Zeppelin-indebted debut album through to their glorious swansong Clockwork Angels.
