I don't have a source for this, BUT I think Rave of Thrones (or whatever they renamed it) is coming back. A few weeks ago someone sent me a link that indicated it was scheduled, but it was vague so I don't know. That one is my priority. It was the best paid party I've been to at SDCC.
I just saw this on SDCC Unofficial Blog:
KRISTIAN NAIRN AT OMNIA
According to his tour page, Kristian Nairn will be returning to Omnia Nightclub during Comic-Con, on Thursday, July 18. In prior years he has brought his “Rave of Thrones” set to the club. You know we have to say it: Hold the door!
Tickets are not yet available, but if like prior years, they will be $20 for pre-sale general admission, or $50 for a VIP package, which includes a $50 gift card to the bar. Doors open at 9 and his set may not be until midnight. The venue is 21+.
