I don't mean an artist who was so horrendously bad it was scary. THIS IS A SERIOUS THREAD!!!
Here are my picks:
Flaw - Payback (Worms and twitching - a lethal combination)
Slipknot - Wait & Bleed (Maybe not now, but when I was 8, I shat my pants)
Aphex Twin - Come To Daddy & Windowlicker (Nuff said.)
I want you to be serious in this thread. Don't mention artists that you hate. I won't accept any "OMG I h8 kAssI n Asslesimpion the R BADddd!" (Even though I'm not fond of either of them)
I'm kind of shocked that so many people have listed "Come To Daddy". Not that it's not true, because I think it's the scariest music video i've ever seen, but wow.
Aphex Twin obviously. But does anybody remember the creepy-ass Tom Petty?
He had two videos that creeped me out when I was a kid:
"Don't Come 'Round Here No More" (I was scarred at the scene they cut a part of Alice out like it was a piece of cake, and by p.o.c. I mean literally.)
"Mary's Last Dance"(he's dancing around, kissing and eating w/ a dead chick. then he puts her in the water and her eyes open. F**KED UP!!)
