In the video below, World Maestro Colin O'Donohoe speaks about "world" instruments and their precarious position in our current world. Colin O'Donohoe compares musicians playing now rare instruments like Qanun or Krar to an endangered animal. The instruments will continue to exist, but will the traditions and knowledge of how to play them survive? 
Colin says that a musician just practicing alone is like an animal in captivity. that musicians need an audience, need other musicians for sustenance. Intriguing talk, and under 5 minutes.
