Query: Unusual rush album

This is by far the most daring album from Rush if you think about it. No Rush album sounds anything like this, not signals or even Power Windows even though the albums were so close to one another. All I'm gonna say is "afterimage" is worth the price of admission alone you can pretty much pick a 2nd favorite after that song, it is CLASSIC!!! Technical, lyrical, original, and thoughtful......Grace under pressure, Rush at it's best.
