In my grail diary, I had every single Rush song, album, bootleg, and music video ever made. I had high-res scans of all their liner notes and album artwork. Every frame of Rush concert footage in existence. Every radio and television interview the band had ever done. Unabridged biographies on each band member, along with copies of their side projects and solo work. I pulled up the band’s discography and selected the album I was looking for: 2112 , Rush’s classic sci-fi–themed concept album.
