During the summer of 1986, Rush was riding the wave of their album *Grace Under Pressure*, which had been released just a few years earlier, in 1984. This live performance at the Rosemont Horizon in Chicago is a striking glimpse into their evolving sound during this era, marked by darker themes and synthesizer-driven arrangements. Notably, the band’s willingness to embrace a more atmospheric, emotionally charged style—exemplified in tracks like "Distant Early Warning" and "Red Sector A"—showcased their shift from grandeur to introspection. Interestingly, on this tour, they also extensively played songs from their earlier works, like "Tom Sawyer" and "YYZ," which kept the crowd engaged and nostalgic. This blending of old and new emphasized their growth while maintaining their roots. It is fascinating to see how well they balanced these elements, proving that even as they ventured into new territory, their core identity remained intact—a hallmark of what makes Rush so revered in rock history.
