It’s nowhere near as technical as math metal, technical death metal, most of japanese metalcore, speedcore. It’s definitely nowhere near as complex as harsh noise.
Don’t get me wrong. I like to listen to Accept and other hair metal bands sometimes but I just can’t listen to it too much after I got out of “metal 4 life” mindset over 10 years ago.
When I want to completely zone out while grinding I usually listen to music that has good strong beat, mind numbing speed or something I can listen to for hours without getting bored.
