(CNN) Katy Perry performed a surprise set on Sunday at a benefit for first responders and survivors of January's deadly mudslide in Montecito, California.

A crowd of more than 2,000 gathered for the "One 805 Kick Ash Bash" fundraiser, named after the area code where disaster hit. It raised nearly $2 million, according to organizers.

"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.
