Calling all Deadheads—rock drumming legend, Mickey Hart, is coming to Boulder and will fill the stage with his energetic beats and wild percussion. Hart, longtime drummer for the Grateful Dead, is known for the ways he and fellow Grateful Dead drummer, Bill Kreutzmann, transcended the conventions of drumming. His recent albums blend music with light, radio waves, and other electromagnetic radiations to produce what Hart has called “cosmic sounds.” Thu 8:30 p.m.
