Author Existence Failure: Neil Peart's death from brain cancer in January 2020 will likely mean the end for any more Rush reunions.
Channel Hop: The band switched to Atlantic Records from Mercury Records for U.S. and international distribution with Presto. In 2011, they switched to Roadrunner Records for the remainder of their career. In Canada, they released their debut on Moon Records, which led to their deal with Mercury. The band then moved to Anthem, where they stayed until their breakup, though Anthem itself switched distribution several times, from Polydor to Capitol, to Sony, to Universal.
Creator Breakdown: Neil's late-90s Trauma Conga Line spurred one collectively. After the death of Neil's only child and wife, Alex hung up his guitars and didn't even listen to music for about a year, Geddy considered the band more or less dead and also broke away from music (returning in 2000 to record his only solo effort, My Favourite Headache). Neil went off on an epic motorcycle journey that took him from Quebec to Alaska, down the West Coast of the United States, and into Belize before going back up and eventually stopping for good this time in Los Angeles. He was still hurting pretty badly as of 2001, when Vapor Trails was in production, if the album's angry, mournful tone is anything to go by.
Enforced Method Acting: Neil wanted his drumming on Clockwork Angels to sound more spontaneous, like "This guy never played that before, and he just barely made it." So instead of spending many hours (or even days, as he did earlier in his career) preparing composed parts before recording, he just listened to each song a few times before recording the drum tracks.
Fan Nickname: Neil Peart was dubbed "The Professor" for his literary lyrics and stone-faced demeanor on stage. When his death was announced in 2020, "RIP Professor" trended on Twitter.
Old Shame: They'd love to forget their first live album, All the World's a Stage.
Same with Caress of Steel and Test for Echo.
Peart seems to regard his early association with Ayn Rand as this after enough backlash. While he admits that her work meant a lot to him in his youth, he describes himself as a "left-leaning libertarian" now, and has downplayed her influence on him in recent years. It's safe to say that most Ayn Rand fans would be fairly horrified by how his position has evolved over the years.
On that 2112 album, again, I was in my early twenties. I was a kid. Now I call myself a bleeding heart libertarian. Because I do believe in the principles of Libertarianism as an ideal because I'm an idealist. [...] Libertarianism as I understood it was very good and pure and we're all going to be successful and generous to the less fortunate and it was, to me, not dark or cynical. But then I soon saw, of course, the way that it gets twisted by the flaws of humanity. And that's when I evolve now into...a bleeding heart Libertarian.
The Pete Best: John Rutsey, their first drummer, was fired from the band due to health concerns in 1974. Still, he narrowly averted this as he played on the debut album. He barely even toured with them before he had to leave due to his diabetes, and that's how he was replaced by Neil Peart, who stayed behind the kit until the band ended 41 years later.
A better example would be Jeff Jones, a founding member of the band, who was replaced within less than a week of Rush's formation by Geddy. Jones later resurfaced as the bassist for Red Rider, of "Lunatic Fringe" fame.
Also of note is Lindy Young, the band's ex-keyboardist well before they hit any kind of fame, who left the band because he was going to college [he was slightly older than the rest of the band]. The kicker, though? Geddy and Lindy are brothers-in-law (Geddy married Lindy's sister Nancy)!
Mitch Bossi who for a very brief time in 1971 was the rhythm guitarist in Rush, before the band reverted back to a three piece, Alex says Mitch became a teacher and wasn't very good at guitar.
Dr. Krieger of Archer infamy is a huge fan. He owned a series of panel vans, each given a Punny Name based on one of their albums ("Exit...Van Left", "Vanispheres", "Caress of Krieger", etc.), and occasionally attempts to cover "YYZ"'s drum solo to no success.
What Could Have Been: Once Neil Peart wrote the "rap" section of "Roll The Bones", the band toyed with several ideas for how to approach it, from working with an actual rapper to getting John Cleese to do a campy spoken word style performance. In the end, Geddy Lee did it and they pitch-shifted his voice to be considerably lower.
Write What You Know: Neil was the bands primary lyricist, and his personal beliefs shaped a lot of his output (in particular, 2112 with Objectivism). Taken to the logical extreme with "Ghost Rider" off Vapor Trails, which was basically a condensed version of his memoir of the same name.
Pack up all those phantoms, shoulder that invisible load Keep on riding north and west, haunting that wilderness road like a ghost rider Carry all those phantoms through bitter winds and stormy skies From the desert to the mountain, from the lowest lows to the highest highs, like a ghost rider.
Word of God: In an interview with Christopher Lee, he mentioned that the second dirty bomb found by police and law enforcement agencies in Melbourne at the end of the fourth season would also have been deactivated. Here's the interview for more details.
