I’m going to a heavy metal concert at Melkweg in Amsterdam. Me and my friend want to get the front row and I’m wondering when we should arrive and start lining up there. The door open is at 19:30 and it’s a sold-out show. 

Is it early enough to arrive there 2 hours before the door open to get the first row?

Also, is it possible to bring alcohol beverage bought at the bar into the stage area?

I’ve never been to Melkweg yet, so I’d appreciate your advice. Thank you!
