Jackhammer
I liked the way your second half went...certainly scarier than the first
. And the Bong-Ra track was a killer! Send it this way too if you don't mind

I think all your choices were solid. The pig destroyer track is great, but fails to scare me. Sleepytime Gorilla Museum, Daisy Chainsaw, Sunn 0))) and Skinny Puppy on the other hand...yikes! Sunn 0))) certainly ripped through my skull. And the Swans track has this uneasy feel about it.
I did know what to expect from most of these (save for Jackhammer's second half alone), but that doesn't take anything away from the experience. I think the next one should be a guessing game.
