I know there's already a Scion/SEMA afterparty with Pete Rock at Transit in Philly.

But if anyone doesn't want to attend that event, check out the official SEMA afterparty at Shampoo on Saturday night. Tickets are $15 at the door, 10 on guestlist. If interested, join www.sinthesisonline.com and click guestlist.

Or you can go to both, since there in the same neighborhood of Spring Garden.
