I think I've been mispronouncing her name for years.
I've seen her on YouTube for I don't know how long. This has been the first time I've ever heard someone pronounce her name.
She's a completely different beast than Neil Peart, but she's very skillful and excels in odd time signatures, which will serve her well in Rush's music.
I expect her to keep only the "necessary" portions of Peart's drum parts and the rest of the time to kind of do her own thing. Either way, I think she'll fit right in with them, though some hardcore Peart/Rush fans might not like the differences. Personally, I think one of the worst things bands can do is to try to replace a member and direct the replacement to do their best to duplicate the original. It usually works so much better when the band accepts the fact that things will change, they'll sound different, and just let another person do their own thing.
That said, she's steeped in Rush-adjacent prog-rock and so while I expect her to introduce a lot of her own parts, it's not like she's going to be a a totally different genre of drummer than Peart was.
