Simulating a seismograph that detects shifts well below the surface, Iceberg chose in March 1993 to sponsor the Rainforest Foundation concert at Carnegie Hall in New York City. Taking turns on stage, singers Tina Turner, James Taylor, Brian Adams, Sting and George Michael raised almost a million dollars for an initiative - saving Amazonia - originally set in motion by Sting and his wife Trudie Styler. Meanwhile, enthusiastically embracing the cause, Silvano, Giuliana, daughter Patrizia and son Paolo joined the Foundation's Executive Committee.
