From the ECA web site, "Kidstock! is the free, annual family event at ECA that features musical performances, theatre, arts education workshops, and activities for kids. Bring the whole family and join us for a day of creativity and fun! This year, the ECA Main Stage will host Tim Noah, The Not-Its!, Alex Zerbe Juggling, and Aaron Nigel Smith. We'll also host performances by Book-It Repertory Theatre (The Phantom Tollbooth) and Thistle Theatre (Mrs. Periwinkle and Possum), as well as face-painting, food concessions, hula hoops, bouncy houses, and a Seattle Shakespeare Company costume photo booth!"
