Washington (CNN)New music festivals across the country will soon have floral headbands and flash tattoos alongside campaign buttons.

Bernie Sanders backers are set to gather on April 21 and 22 -- before the second weekend of the music and arts festival Cochella -- for what they're calling "Berniechella," a free event in Old Town Coachella, California, according to the event's Facebook page.

Artists set to perform include Alex Ebert, lead singer of Edward Sharpe and the Magnetic Zeros, DJ Shepard Fairey and the band Ozomatli, among others.

"It's a party of people who are in support of a particular candidate," event organizer Tizoc DeAztlan told The Desert Sun.
