Rush was nothing close to Heavy Metal after Hemispheres, they started sounding more like The Police.
rush is a classic power trio.
Oddly the police started as a quartet
Yes, there was a time there when they sounded like the Police or even New Wave bands. After they got back together in around 2000 they rid most of their music of the keyboards and went back to their roots.
Below is “Headlong Flight” from their last album. It isn’t heavy metal (I never classified RUSH as heavy metal though) but it sure rocks though imho:

I always found that most of their albums took awhile to get used to when they first came out. They were often quite different than their previous ones.
