Chris Thrash was just seven when his parents took him to Showbiz Pizza Place in Columbus, Georgia, in 1982. Amid the blaring video games, ball pits, and steaming-hot pepperoni pies, he found himself plopped down in front of the restaurant's stage as the houselights went down.

It's a stifling July day in Pittsburgh, and Gregg Gillis, a.k.a. Girl Talk, is dressed accordingly: soccer shorts, white T-shirt, and a bandanna around his forehead. After releasing 2006's Night Ripper, the pop-savvy cut-and-paster quit his biomedical engineer job and went from playing tiny underground venues to chaotic dance parties around the globe.

The missing link between punk and riot grrl wasn't a band or even a fleeting subgenre, but an amazing 1982 Paramount music-biz satire that was never properly released, seen only on late-night cable, crappy bootlegs, and at art-house revivals.
