Sixty Minutes had a story last night on children in either central or south america playing instruments made from re cycled trash.  It was amazing.   The children, and their orchestra will be the subject of a documentary to air in the fall (in the United States) called the Recyclers.  Instruments were made from oven tins, coins, tin cans.  Instruments were mainly string instruments, but I wouldn't be surprised if a piano was eventually attempted.  It proves what I have always believed, that music cannot be stopped.  Check out the news piece on CBS Sixty Minutes.
