Laguna Woods Village resident Rebeca Gilad formed the Community Bridge Builders choir after a tragedy rocked their city.
"Those things that you cannot say just in words; when you put music, it changes everything," Gilad said.
The choir is made up of residents from all backgrounds.
"It suddenly feels like angels singing and peace is possible," Gilad said. "It's all one family. This is our family. This is our home. This is our neighborhood and that's what so magic about it. It's magic."
In May 2022, a gunman walked into Geneva Presbyterian Church and opened fire on Taiwanese parishioners, killing one and injuring five others.
Deadly OC church shooting was 'politically-motivated hate incident,' authorities say
Authorities said the attack was fuel by hate.
"Out of that hatred this group of people in the community got together to learn how to speak up, what to do when that happens and to stop being bystanders," Gilad said.
The choir got together to film a music video on Wednesday. The group sang a tune titled "One Song" and speaks to the power of being united as one voice.
Mitchell Jay composed the song.
"I was inspired by older songs. 'We Are The World' and 'Imagine' were kind of the two songs that inspired me and the feel that they give," Jay said.
The song is also sang in different languages including Spanish and Korean.
"Music is international language so we can say this in ten different languages, play the notes for ten different languages, it comes out the same," said Carmen Pacella, musical director of Community Bridge Builders.
The group believes the song's simple message connects people in their community who may otherwise not have an opportunity to come together.
"They're having fun and they're coming back," said Willie Phillips, who serves as Community Bridge Builders' vice president. "It's not just a joyful thing, they're having fun while they're doing this. It's a blessing to everyone in the community."
Community Bridge Builders hopes their choir inspires others to translate their message of unity into the communities one song at a time.
