Missy Elliott's seminal 2001 hit, Get Ur Freak On, is one of those songs that can't really be covered.
Instead, you can only try and improve upon it or even add something extra to it. Eric Moore, who was formerly the drummer for funk metal group Suicidal Tendencies, posted this video via Aquarian Drumheads a few weeks ago online and it's since gone viral because, well, you'll see.
Take a look. The song itself kicks off around 1.09 and you'll want a good pair of headphones to really enjoy this.
