Alpha and Whiskey's torture music!

Okay, so in the beginning of Season 1, Episode 12 there is the flashback which shows Alpha and Whiskey being scary criminals. When they start getting a bit frisky there's an awesome bit of সঙ্গীত that plays in the background. What is it called and where can I find it?

I know the first bit of সঙ্গীত is Roy Orbison, just want to know the other bit!
