Here is a really good example of a Skrillex remix and taking it to the next level. The first video is an original piece by Benny Benassi....which is okay. I don't dislike it but if you listen to this....then listen to the Skrillex remix of it and you'll see that he CRUSHED the original.
Now give the Skrillex version a listen and see what you think.
If you're still with me and not necessarily a fan or familiar with his work check out an original piece in this video.
Oddly enough Skrillex strikes an incredible resemblance to Corey Feldman. LOL
