Unreleased music by Beyoncé was among several items stolen from a vehicle in Atlanta, just days before the singer's four-night Cowboy Carter tour stop in the city, authorities have confirmed.

Thumb drives containing Beyoncé’s unreleased music, future set lists and more have been stolen from her lead choreographer and one of her dancers, according to the Atlanta Police Department.

The concert marked her last of four shows at the stadium on her Cowboy Carter and the Rodeo Chitlin' Circuit Tour.
