Andy Graham had a problem. He wanted to play the drums and the didgeridoo at the same time, but he needed his hands for both. There wasn’t a real answer to his dilemma, so the local musician created one—the Triple Didge Rack, which supports his didgeridoos so his hands are free to bang out rhythms on the drums. He’ll be using the device when he performs at Poppy Hop, a celebration of the fifth anniversary of the Children’s Museum of Sonoma County. Besides Graham’s performances, the event will also feature a DJ’d dance party, birthday-crown making, and Hula-Hoop lessons. The party will be held on June 8, 10 a.m.–2 p.m., at the museum in Santa Rosa. It’s free with admission ($9–$12, or free for babies younger than 12 months old). Find out more at cmosc.org/poppy-hop.
