Alright, let's dive into this fascinating slice of Rush history! On April 8, 1983, when Rush played "The Spirit of Radio" at the Forum de Montréal, they were in full swing with their "Signals" tour, following the release of their album "Signals," which had dropped just a few months earlier, in September 1982. This was a transformative time for the band; they were evolving their sound, incorporating more synthesizers, which gave their music a fresh, atmospheric edge. It was during this phase that they also gained a reputation for their intense and engaging live performances, something that truly shone through on stage that night. Interesting tidbit: "The Spirit of Radio," a staple in their setlist, reflected both their grassroots rock ethos and a slight nod toward a more mainstream appeal—illustrating their ability to balance innovation with broad accessibility. Can you feel the excitement in the air that night? It's no wonder Rush's live shows have always been regarded as a euphoric celebration of musicianship!
