I wasn't formally familiar with Amplifier until October's artwalk. However, I've run across their cause many times in the last year without really knowing it. If you were at the Seattle (or other) Womens' March an many other events, you've been touched by Amplfier. This happens to be the Seattle "chapter".
A back lit video on the window of the space caught my attention and that was what drew me in.
Shepard Fairy's stunning posters are part of the movement.
A well attended event, quite informative and they had a lot of swag!
Amplifier calls themselves, "an art machine for social change". Works for me.
