The Chain Reaction is a hole-in-the-wall venue in Anaheim that primarily books bands you'd see at Warped Tour.
I don't remember why, but I subscribe to the Chain's mailing list.
An excerpt from this week's e-mail:
yo, so PIEBALD is playing a special show here. its $5. PIMP MY RIDE will be here filming it because they made the band's van run on vegetable oil.
Xzibit and Piebald. I gotta see this.
