Katy Perry surprised One805’s Kick Ash Bash attendees by performing acoustic versions of her songs, “Part Of Me” and “Firework” at the benefit. The event honored First Responders and survivors of the fire and mudslides in Montecito, California while raising funds for emergency equipment, counseling services and survivor relief.

“This means the world to me,” Perry told CNN. “This is where I flourish. My heart was broken by the tragedy, the mudslide. I’ll do anything to help this community.”

Perry grew up in nearby Goleta.

In an emotional moment backstage, Perry hugged 14-year-old Lauren Cantin, who was among those rescued from mud and debris.

Cantin lost her father in the lethal flow. Her 16-year-old brother, Jack, is still missing, but her mother survived.

Perry told the teenager, “You can sing.”
