NPGMC has sent out an e-mail to premium members on how they can get advance tickets to the afterparty tonight in Detroit. Tickets are $25 each for premium members (not sure how much for the gen. public), and can be purchased well before the general public.

In the words of NPGMC:
"THERE IS NO PER4MANCE SCHEDULED, just an afterparty."

If you did not receive the e-mail, contact the NPGMC.
