What is the music in the 'Dazed and Confused' mission in Far Cry 4

I've just been playing the Dazed and Confused level and was wondering what the music was. It's a mission with Yogi and Reggie done under the influence of drugs.

I was curious if it was a normal track or something written for Far Cry 4. I've tried googling for it but as there's a Led Zepplin song of the same name it's a bit difficult to find out.
