On Saturday night (Sept. 26), Carrie Underwood gave her time to sing at a MusiCares benefit concert that raised over $146,000 for the charity organization.

The concert was held at the private vacation home of jeweler Johnathon Arndt, located in Brentwood, Tenn. In addition to providing his 18,000-square-foot home as the event's venue, Arndt and his partner, Newman Arndt, underwrote the show, meaning that all of the money raised went straight to MusiCares.

“We said, ‘We’ll take care of everything. You enjoy the sales of the tickets,'" Arndt tells the Tennesseean. “We truly believe in giving back to the community and giving back to the organization 100 percent.”

The newspaper also reports that Arndts are the first people ever to cover the full cost of a MusiCares event, allowing all of the funds to go directly to the charity itself, which helps musicians and members of the music community by providing financial support to those in need.

This fundraiser wasn't the first time that Underwood and Arndt have crossed paths: The jeweler designed the singer's yellow diamond engagement ring.

Underwood is set to release her new album, Storyteller, on Oct. 23. The project features her new single, "Smoke Break," and is available for pre-order on Amazon.
