Trimpin: The sound of Invention is a wild ride through the sonic world of an eccentric creative genius. Artist /inventor/engineer/composer Trimpin has never been represented by a gallery, a dealer, or a manager, and doesn't have a cellphone or a website yet his freewheeling sculptures and outrageous musical experiments are cherished by artists, musicians, and museums all over the planet. Filmed over the course of two years, this feature documentary shows the iconoclastic artist, experimenting with the Kronos Quartet on a toy and electronic instruments, building a 60-foot tower of self-tuning, automatic electric guitars, designing a perpetual motion sculpture in a glass foundry, creating giant marimbas that convert real-time earthquake data into music and always (quite deliberately) getting into creative trouble. A humorous, in-depth investigation of a creative genius whose self-made world resembles both Santa's workshop and Frankenstein's lab.
