Harry Partich Playing the Bamboo Marimba. Caption reads as follows:
The BOO, or Bamboo Marimiba, has 64 sections of Phillipine bamboo with vibrating tongues cut in the open ends. The bamboo arrived in San Francisco under the bunk of a base fiddle player who, when departing for the Orient, asked casually, "Can I bring you anything?" Said I (and immediately forgot it), "Yes, a load of giant bamboo."
