They were Xero before Chester joined, when he joined, they made the EP and then a band with a similar name asked them to change it, and then they were Linkin Park.
I don't know if anyone else here has noticed but the auction never finished. The seller cancelled the auction. I wrote to the seller asking why and he wrote back saying that he had changed his mind. Lol...I guess he finally realized he was selling something that is almost priceless.
