The world is a darker place since Robin Williams passed away. While everyone grieves in their own way, the folks at 775 After Dark are choosing to celebrate the humor and joy that Williams left in our hearts. This week, the venue hosts an experimental art show and concert, the self-described “cyberpunk mini-fest” known as Throbbin Williams. Nine bands take to the stage for a blistering day of music. Oakland electro punks Diesel Dudes and Napa synth sensation Magnanimous headline the event, which happens on Thursday, Oct. 23, at 775 After Dark (Aubergine), 755 Petaluma Ave., Sebastopol. 6pm. $5–$10. 707.829.2722.
