I would say,that even your typical d.j. is a musician,to some extent,as it requires arrangement skills -which in of itself is creative,as well as having a sense of rythym.
D.j's are simililar to a conductor in an orchestra & this particular fellow is orchestrating quite a bit-all at one time...exceptionally well.
I of course,like dance music,but this guy's stuff is not really my thing,as it's more noise than melody & I just could not sit through almost 40 minutes off this stuff-ouch!
