At the Kongresshalle in Berlin O+A made a resonance installation
in support of S.O.S., a Solar Art Work by Peter Erskine.
A tuning tube was placed at the entryway to collect and transform
the sounds of busses, voices of visitors, passing cars, and the
fountain into a harmonic series. This Set of real-time melodies and
harmonies was projected from a single planet speaker pointed up at
the overhanging parabolic cement roof. The resulting ambient drone
composition was a coupling of the architecture and resonance. The
piece resonated from Spring to Fall equinox.
