Chris Charucki, a prominent production manager within the Grateful Dead family, has passed away. As explained by in a 2003 interview, Charucki first became connected to the Grateful Dead when he began working with them in 1993 through Ultra Sound. In the time since, he continued working with the band’s various offshoots, including touring with FurthurRatDogBob Weir, and Dead & Company.

Rest in peace, Chris. You will be deeply missed.
