Very sad news, I remember the impact of Neil Pearts playing on me to this day. It was 1984 and I was 14 years old listening and navigating a mixture of late UK punk and new wave drumming (the Clash meets Japan). Then a friend played Spirit of Radio at full blast through his dads new HiFi. Although it was old music.... Holy cow....the beat placement the propulsion and sheer joy of life just exploded. No more introverted nihilistic bs...closer to the heart yes.
The first concert I ever saw was Rush's Fly By Night tour, in a hockey arena in North Bay Ontario.
Peart's passing is a bigger deal here in Canada. He was quite a cultural icon, and a member of the Order of Canada. For Canadians of a certain age, many, many good memories are associated with the music of Rush, and Peart's passing brings up all of them.
