Hey, fellow Katatonian!
Well, judging from the fact that you listen to death metal, I (fucking highly) suggest you pick up all three of Strapping Young Lad albums (fourth coming out early next year... Febuary ain't it?). I haven't heard Ocean Machine yet, but other than SYL, I've got Terria, Infinity, and The Physicist. I love SYL about a gazillion-thousand times more than any of the above three, but The Physicist is fucking killer. I honestly don't care for Terria, but Infinity is okay (now ducking from the oncoming verbal blows from other Devy fans).
SYL: can't go wrong.
Anything else: listen to it first and then you decide.
ENJOY!
