I don't know these artists (which is not meant to be a dig at them; it's most likely more a reflection of the divide between public art and non-public art). More of their work on their web site here. Details on the meeting:
Meet the artists 6 to 8 p.m., Wednesday, June 16, at the Wing Luke Museum of the Asian Pacific American Experience, 719 South King St.
During their visit to Seattle, Harries and Héder will gather information about the First Hill Streetcar project and the neighborhoods and communities along the streetcar line. At the presentation, the artists will speak about their past projects and share initial observations on integrating artwork in the streetcar line. Harries and Héder will answer questions and accept written comments from the audience. The artists will create design proposals for the artwork following their visit.
...A panel of art and design professionals selected Harries and Héder from a pool of 200 national applicants. The selection panel included arts professionals who live and work in neighborhoods to be served by the streetcar. The artist selection process occurred prior to final approval of the streetcar route by the mayor and City Council to allow the artists to begin collaborating with the streetcar design team during the earliest stages of the streetcar project.
