This will be a symphony of quiet. Debra Baxter has been known to cast a throat in alabaster. It would make a noise, except it's too gorgeous. Heide Hinrichs lays pearls across a concrete floor. They'd roll away, except they're attached by string so thin it's invisible. I can't wait to see these two Seattle artists in adjoining rooms, whispering in all caps.
