The HFStival has become one of the country’s largest and longest-running alternative radio bashes and this year, it will bring more than 29 performers to entertain an anticipated 90,000 fans.

The event sold out in a record 47 minutes and boasts a lineup featuring Rage Against The Machine, Deftones, Stone Temple Pilots, Cypress Hill, Godsmack, Bloodhound Gang and others.

The concert, sponsored by radio station WHFS-FM, happens on three stages and also features attractions such as the Trancemissions techno tent, Non-Profit Action Fair, and virtual reality rides.

The second stage, which is for “Locals Only,” will be headlined by Jepetto and Mary Prankster.

Socially-conscious concert-goers will have booths and information available from 62 organizations, representing interests from the Camp Fire Boys & Girls to the Fourth of July Hemp Coalition, at the Non-Profit Action Fair.

A portion of the proceeds from the HFStival will benefit Amnesty International USA and Friends of the World Food Programme.
