This was a big interactive sound installation set up for several days on Market Street in San Francisco as part of an event called The Market Street Prototyping Festival in the fall of 2016. It incorporated several types of sound components. Most were mounted in a three-part wall, plus there were three separate musical benches marked “sit or play”. A gazillion people came by and played the instrument during the three days it was in place; it was a blast. For a full description, see here.
Regrettably, I didn’t make good sound recordings of the installation before it was disassembled, so there’s no audio clip for this one.
Play Hear was created by a team consisting of Adam Fong, David Samas, Sudhu Tewari, Peter Whitehead, Ben Carpenter and Bart Hopkin.
