On today’s date in 2002, just a little over one year after two passenger jetliners had crashed into the twin towers of the World Trade Center in New York City, the New York Philharmonic gave the premiere performance of a new work by the American composer John Adams.

Entitled “On the Transmigration of Souls,” this high-profile commission sought to address a nation still in shock and grief at the terrorist attack of September 11, 2001.

"I realized right up front that the public didn't need any more reiteration of the narrative of that day,” Adams said in an interview. “Certainly it didn't need some tasteless dramatization of the events… If I was going to do something meaningful, I was going to have to go in the opposite direction."

Adams chose to set some of the words scribbled on posters plastered around Ground Zero by families searching for their loved ones. "They were a mixture of hope and a slowly dimming acceptance of reality," Adams said. “When people are deeply in shock… they don't express themselves in fancy language… they speak in the most simple of terms."

Adams said he hoped his new piece would provide "memory space,” a musical work that could be at once a platform for either communal or personal reflection.
