what is the best time to arrive before a concert?

I usually get there about an hour early. I usually smoke pot in the parking lot and have some beers before going in. Good times.

You have to consider whether there is parking in the area that might pose a problem. This is the main reason to get there early enough to be able to get in and out of the place..

Be there as soon as the doors open. I guarantee others will be there and there will be a long line.
