tamtam refer to their work with the sentence:
"the sound environment is becoming the instrument, the instrument is becoming the sound environment." their instrument is, for all intensive purposes, not only a sounding object that we are well familiar with. it is also the space itself where sound lives-the acoustic and psychoacoustic fields that enable us to extend our accepted senses to hear the habitual and the everyday as something extraordinary.

cage always discussed the space between the notes-the place that is
neither sound nor silence but in suspension and waiting. In their search for a new sonic language-a language where sound no longer evolves on the horizontal, left to right plane of musical history but from foreground to background, outside to inside, sounding always on the threshold of disappearance-tamtam are also creating a new language of listening. one where the space between is filled with the listener's own experience.
