what the video doesnt tell or show you is that both armin and tiesto actually had the same management company and production company for years.
armin and tiesto was both under dave lewis management for years.
Infact dave got them both to the top, but when Tiesto wanted dave to drop all his other artists and concentrate soley on him they had a big fall out and parted there ways and tiesto formed his own management company.
Dave lewis management manages armin, gareth emery, menno de jong, markus schulz among others, so why the heck would he work soley on tiesto????
Also the part about MC stretch working on both tiesto and armin concerts, not being funny but he's a solo artist he can work for who the hell he wants.
Also if the solo concerts was innitially produced by same production company then thats possibly why theres similarities in the concerts.
Epic Fail
