ACM Lifting Live teamed with Borderline Bar & Grill, the site of a mass shooting on Nov. 7, 2018, that left 12 patrons dead, for a benefit concert on Feb. 11 at the Thousand Oaks Civic Center in Thousand Oaks, Calif.

Hosted by Charles Esten, the one-night-only concert featured Trace Adkins, Jimmie Allen, Charles Esten, Cassadee Pope, Tyler Rich, Runaway June, Kelsea Ballerini, Morgan Evans and more. All net proceeds from the event will benefit Ventura County Community Foundation’s Conejo Valley Victim’s Fund, which supports recovery efforts related to the shooting at Borderline.

In addition to the country talent on hand, there were a number of celebrities in attendance, including actor Casey Affleck, actress/singer Hailee Steinfeld and model Sabina Gadecki, who is engaged to Tyler Rich. Arnold Schwarzenegger, the former governor of California, also made a surprise appearance. After Charles Esten introduced him, Arnold shared some words of support for the crowd before introducing Trace Adkins’ performance.

“I was inspired by how these fantastic artists and the community came together to support the victims and their families,” said Arnold via Twitter. “This is America. #BorderlineStrong”
