If you venture off the hill tomorrow and end up stopped at the Fremont Bridge, you’re in for a treat while you wait! After a summer-long residency at the bridge, artist Kristen Ramirez is showcasing her public art display “Bridge Talks Back: A Sound Artwork” this Saturday.

Between 1-4 p.m. tomorrow, Saturday, September 26, can enjoy a choreographed performance every time the bridge opens. A sound collage will blast over the bridge’s sound system (including clips of boats, birds and bells) and one hundred volunteer performers and musicians will be participating live (there will be 16 different horn players located in each of the structure’s four towers).
