Lots of older bands mentioned but I don’t think AC/DC has been mentioned… whaaat. Back in Black and so many more.
And like cmon, Guns N Roses - Sweet Child o’ Mine. Duh.
Ozzy - Crazy Train. Another duh.
Led Zep - Kashmir. Can’t beat that riff.
I also think Tool has had some banger openings. Sober, Jambi come to mind.
I grew up on nu metal and am not ashamed of it.
Deftones - Change (in the house of flies) is iconic. Many more. NIN - Closer, Hurt. Marylin Manson - Beautiful People.
Newer bands…. Gojira, Spiritbox, Architects go pretty hard.
