Have you seen their excellent documentary film "Beyond The Lighted Stage"? If not, then I highly recommend seeing it if you are a fan of the band. I think even folks who aren't particularly interested in Rush, but enjoy a good documentary would get a kick out of it. With excellent archival footage, interviews with the band and testimonials from Gene Simmons of Kiss (who unbeknownst to me actually gave Rush their big break in America by taking them out on tour on their first record), Taylor Hawkins of Foo Fighters, Vinnie Paul of Pantera, Billy Corgan of Smashing Pumpkins, Kirk Hammett of Metallica and others, you get a good look at the band from their humble beginnings in Canada up until their last release, 2007's Snakes And Arrows.
