I got this email from the House of Blues. Ticket sales must be pretty low if they're doing something like this. I don't think they've done this before, at least not that I'm aware of.
They're offering tickets to see Snoop Dogg on June 27 and The Game on June 24 for $75 a ticket. They're both performing at 4th and B. You have to go through ticketmaster. Sorry.
So if you're interested, the password is BALLER.
