Which music festivals use facial recognition tech?

Evan from Fight for the Future writes, "We just launched a new scorecard showing where major music festivals stand when it comes to using invasive and racially biased facial recognition technology on fans. Bonnaroo, Austin City Limits, Electric Forest and others have committed to not using biometric surveillance, while Coachella, SXSW, and Riot Fest have refused to make the same promise. Headlining artists like Tom Morello of Rage Against the Machine and Amanda Palmer are backing the campaign. Find out where your favorite event stands, and contact the ones who haven't responded."
