First of all, Afrojack was over an hour late, proffering some lame excuse about getting a flat tire. Next, once he finally began, his "performance" was mediocre. Lastly, if these DJ's want to be treated as celebrities, they should practice some degree of professionalism.
Regarding R3hab, his performance was UNBELIEVABLE! What a surprise (since I wasn't familiar w/ him prior to that night). Afrojack should have been taking notes...
