While certainly not his best (I think that title may be reserved for the popular Scary Monster and Nice Sprites), Bangarang is definitely worth the watch (and the listen!) for all fans of Skrillex. In my personal index, it ranks in this student's Top Five, up there with the songs mentioned in this very post.
If you like Bangarang, then check out some more of Skrillex's catchy dubstep tunes with First of the Year (Equinox) or Scary Monsters and Nice Sprites, both of which I'm sure you can find on YouTube with a cursory search.

Here's some more info on the illustrious Skrillex, from Wikipedia:
"Sonny John Moore (born January 15, 1988), better known by his stage name Skrillex, is an American electronic music producer and singer–songwriter. Raised in Northeast Los Angeles and in Northern California, Moore joined the American post-hardcore band From First to Last as the lead singer in 2004, and recorded two studio albums with the band (Dear Diary, My Teen Angst Has a Body Count, 2004, and Heroine, 2006) before leaving to pursue a solo career in 2007.
He began his first tour as a solo artist in late 2007. After recruiting a new band lineup, Moore joined the Alternative Press Tour to support bands such as All Time Low and The Rocket Summer, and appeared on the cover of Alternative Press' annual "100 Bands You Need to Know" issue."
