Though she is known to many as the director of big, broad '90s studio comedies such as "Wayne's World" and "Black Sheep," Penelope Spheeris is revered by others for her trilogy of L.A.-set music documentaries, "The Decline of Western Civilization" Parts 1, 2 and 3. The films have just been released as a boxed-set by Shout! Factory, allowing audiences for the first time to consider them all together while highlighting their achievement within Spheeris' career and their deeper effect on her life.
