Haha SALEM have screwed Britney Spears' 'Till The World Ends', twisting the sultry dancey-ness of the original into an apocalyptic feeling, melancholic jam.
If you haven't already listened to SALEM's LP 'King Night' (out now on I Am Sound records), it's definitely worth checking out; the record is a really great example of how chopping and screwing can be used to make epic, juddering bassy music without neccesarily becoming repetitive or overwhelmingly sluggish. They've recently put out 'Sick' as a single, with a typically SALEM-esque video accompanying the release.
