What time does this usually start at? Would like to know so i can decide how early i should arrive in Boston.

Usually 8, but there's no guarantee it'll happen this year.

@marino: Does Harmonix usually announce it via twitter before PAX?

@jedted: Yeah. You have to buy tickets.

I'm hopping they do it again, I missed out last year because tickets sold super fast so if it does happen I'm hopping I have better luck this year.

I hope they do it. This will be my first PAXEast and I have always heard how fun this party was.

They're doing a party on Friday next to the convention center, as well as a thing on Sunday. No Thursday night Rock Band.
