Grammy award-winning rock band Linkin Park is throwing a private concert at a secret venue at the end of August to help Japan's tsunami victims from the deadly 8.9 earthquake in March.

The band is asking fans to log onto

Fans who raise $500 by August 24 will earn two tickets to the secret show.

The 50 top money-raisers will also get a meet-and-greet session with the band members, and the top 10 will receive instruments signed by the band.

The person who brings in the most money gets an onstage spot from which to watch the show.
