We’re 40 this year. KUOW’s Marcie Sillman marks this milestone in her three-part series on public funding in the arts Culture Shock. The segments are scheduled to air next week, but you can listen online now. Sillman looks at the history and the evolution of the Seattle Arts Commission, talks with arts leaders and elected officials about the role of public funding in the arts and reports on how arts groups are redefining their work in response to the recession.
