CODA 1997 – Super-8 Film

1997  San Francisco –
When you could drop off Super-8 film at the local supermarket for development. 
One of the first audio recordings I did with the trumpet. Recorded in the Sound Column at the Exploratorium – if you asked the receptionist at the museum real nice, she would give you the key to the Sound Column, located outside in the park, inside one of the large columns of the old World’s Fair architecture. The column stacked pitches when you struck the nodal instruments, so when you moved your head vertically you would hear different tones (dunno exactly how that one worked, but it was totally inspiring – got me on my way to wanting to work with sound…)
