Are you registered to vote? Pearl Jam & Dave Mathews want to make sure that you are. Here's how. Pearl Jam, Phish, Jeff Tweedy, and Dave Matthews want to make sure you're registered to vote.  As part of National voter Registration Day Monday, (Sept 22) hundreds of musicians and celebrities joined forces with the nonpartisan group HeadCount to encourage first-time voters and young people to get registered.  They all posed for photos that have since been posted to the HeadCount Facebook page along with a link to a Rock the vote-powered online voter Registration form.

In order to be ready to vote in the November 4th General Election this year, you will need to be registered to vote, by October 10, 2014.

Here is all the information, including the online forms and where they need to be submitted to.
