On September 11, 2001, Perry was scheduled to perform at the World Trade Center's lunch-hour jazz concert series between 11 a.m. and 1 p.m. As fate would have it, he was spared from the devastation of the terrorist attacks on the Twin Towers.
However, for the next few years, he sank into an artistic depression, and did not record again until invited by longtime friend Don Grusin, who he joined in September 2003 for a collaborative venture titled "The Hang."
This CD/DVD project was nominated for a Grammy Award, and included Dave Grusin, Harvey Mason, Patti Austin, Natali Renee, Abraham Laboriel, Alex Acuna, Ernie Watts, Lee Ritenour, and others.
After returning from a South African trip, Perry became ill during a performance with Pieces of a Dream, in October 2009, at Southern Connecticut State University.
Two years after its release, Say Yes continued its steady climb to become one of Billboard's 2014 top smooth-jazz singles, featuring Perry in a classic duet cover of Where Is the Love?
