Over the 4/20 weekend, a pair of jam-centric acts brought their talents to Denver as Jason Hann delivered his Rhythmatronix at The 1Up in Colfax on April 18. The ensemble that evening featured Hann along with Steve Kimock, Steve Molitz, Raul Pineda, Fareed Haque, Todd Stoops and Andre Manga. On April 20, Billy and the Kids delivered Grateful Dead favorites at the Ogden Theater. Joining Kreutzmann in this new project is Aron Magner, Reed Mathis and Tom Hamilton. On this night, they were also joined by Big Gigantic’s Dominic Lalli. Ben Wilson shared some photos from the shows.
