Last year Venture Bros. composer JG Thirlwell performed the show's tiki-bar-meets-secret-lair soundtrack at Brooklyn's Prospect Park with his big band outfit Steroid Maximus. Here's recently released footage of Thirlwell and company's snazzy performance.

The above video is a medley of the instrumentals "Fumblestealth," "Bolly," and "No Vacancy (Venture Bros. Theme)," and the below video is a live performance of the VB track "Gawker."
