In the 20th century, Frank Zappa made his mark as a popular musician unlike any other in America. A weird, wild, eccentric, iconoclastic attitude, guided by a firm intellectual integrity, drove his music making it distinctive. This excellent documentary covers his life and work with superb archive footage taken from across the decades. From his early taboo-challenging creations, his outspoken efforts against the political forces determined to censor him and his constant quest for new artistic challenges, Zappa was possibly the most innovative musician of his generation, dangerous but ferociously compassionate.
