Fan-filmed video footage of Lady Gaga taking a “dance break” with Lady Starlight to the sound of METALLICA’s “Metal Militia” during her August 6, 2010 performance at the 2010 edition of the Lollapalooza music festival in Chicago on August 6, 2010 can be viewed below.

“Metal Militia” is the 10th and final track on METALLICA’s debut album, “Kill ‘Em All”.

Originally issued on July 25, 1983 through the independent label Megaforce Records, “Kill ‘Em All” was recorded in two weeks on a miniscule budget in upstate New York. Although only 1,500 copies were initially pressed, the album was reissued by Elektra Records after the band signed to that label in 1984 and has since been certified triple platinum for sales of more than three million copies.
