If im going to a My Chemical Romance concert and it starts at 7 when should I get there to be in the front?

Im going to a MCR concert in may and I want to be front and center. So im figuring since they are a huge band i would have to wait outside for a pretty long time to be up front. So, if the concert starts at 7:00 P.M. I was wondering if anyone would know what time I should be there by to get up front? Should I camp out overnight? Thanksss(:
