In Through The Out Door, Rush's 8th studio album, received universal praise from critics. It was the beginning of their long-lived commercial success, culminating in a Rolling Stone magazine cover story in 1979 proclaiming them the coolest rock band ever.
The album was pulled from shelves by concerned parents when it was revealed that there were hidden messages recorded backwards throughout the album, referring to "butt stuff". It was later re-released with the less vulgar title "Moving Pictures".
