I've seen Rush a half dozen times and am never disappointed with their performance. On July 15, 2015, Alex, Neil and Geddy performed perfectly, with passion and precision, covering their 40 years together with a great selection of their songs. With so many to choose from, you were bound to miss a few favourites. But it was great to hear some that hadn't been played live in a long time. The biggest drawback, and sole reason for the low rating, was that the quality of the sound was awful. Although everyone knows certain stadiums are notorious for poor sound, I have been to some really great sounding concerts in Calgary's Saddledome. Unfortunately this time, someone did not pay close attention to getting it right. Hard to believe with today's technology that it can't be better. A good start would be a few decibels less loud, and stop over-accentuating the deep, deep bass. Any sound engineer should know this drowns out the midrange. Please stop trying to cater to the dubb-step (and other new music) crowd. It doesn't suit RUSH and shouldn't be used.
