This month seems to be the "Aaron Kwok Concert Month". This 'heavenly king' is having 3 concerts in both Canada and the US. These concerts are probably his "practice" concerts to help him get a feel from the audience and prepare him for his huge one in HK this November.

May 26th - Aaron Kwok, Reno, NV (Reno Events Center), 8pm
May 27th - Aaron Kwok, Las Vegas NV (Orleans Arena), 8pm
