Several major touring artists--including Jack Johnson [ tickets ], John Mayer [ tickets ], Ani DiFranco [ tickets ], Wilco [ tickets ], Foo Fighters [ tickets ] and Megadeth [ tickets ]--have joined forces with the nonpartisan voter registration group HeadCount to sign up new voters at their concerts this year.

Santana [ tickets ], My Morning Jacket [ tickets ] and The Decemberists [ tickets ] recently aligned with HeadCount, joining longtime supporters such as Dave Matthews Band [ tickets ], The Allman Brothers Band and members of The Grateful Dead and Phish.

Volunteers will stage voter registration drives at more than 1,000 concerts this year, with a goal of registering at least 100,000 voters. The non-profit group will have a presence at every US concert on the Dave Matthews Band, Johnson and Mayer summer tours. HeadCount registered more than 12,000 voters at Dave Matthews Band shows in the summer of 2004, an all-time-record for a single concert tour, according to a press release.

HeadCount also will have voter registration teams at more than a dozen major festivals this summer, including The Bonnaroo Music & Arts Festival, Virgin Mobile Festival and Farm Aid.
