Attain an editorial assignment from a music media outlet, such as a print, online or TV outlet. Warped Tour requires this. They won't give you a photo pass to take photos for your blog, Twitter, Facebook, YouTube or other similar website or if you're just trying to build up your portfolio.
Send an email to Libby Coffey ([email protected]) and Bari Lieberman ([email protected],) but not before March or April of the year you want to take photos at Warped Tour. In the email, request a press request form.
Fill out the press request form and mail it back to the Libby Coffey and Bari Lieberman.
Send a recent copy of your publication, if you work for a print outlet, to Libby Coffey and Bari Lieberman at MSO in Sherman Oaks, California.
