Artist Josiah McElheny has gone and made a big deal of himself in the world, but his roots are in Seattle—and in conceptual art and studio glass. The Last Scattering Surface, his postmodernist Big Bang installation, will spend this spring at the Henry Art Gallery. To kick off its tenure, the notoriously shy but spectacularly eloquent artist (who's also a writer) will give a talk. Afterward, he'll get on a plane and fly away again.
