It's a vast list. Judas Priest. Iron Maiden. Metallica. Suicidal Tendencies. AC/DC. Rush. Primus can sound pretty heavy at times. Love a lot of their tunes. Black Sabbath of course. Both Ozzy and Dio with or without Sabbath. Queensryche has some good stuff. Accept has a couple good tunes. Krokus, Saxxon. The list goes on and on

My most recent discovery has been Thought Chamber, featuring Ted Leonard of Spock's Beard on vocals, and Michael Harris on guitar. I've loved shred guitar for as long as it's been a thing, and I think Michael Harris is the best of the genre. Anyway, they're a phenomenal band. I totally recommend them.

Maybe Cream, maybe the Jimi Hendrix Experience. Are The Doors hard rock??

Why? Probably because I heard them at an early impressionable age. They were a big part of the soundtrack of my youth.

I love RHCP. I have been a fan of their music since my twenties, and I guess I sort of grew old with them. It’s been amazing hearing their music evolve over the decades.

Man I'm older, not like todays kids so I'm have to say bands like Judas Priest, Rush, Motorhead, and Slaughter

Led Zeppelin, just because there music fits my style, and there are other bands that come a close second. :)

The Doors meant the most to me in my teen years, but now I dunno anymore, I love some songs by The Black Keys.

Linkin park, Green day, And few songs from old bands.
