Also during 2009, five poems from Mattie's Reflections of a Peacemaker were set to music by Chicago composer Lita Grier and released on record by Cedille Records. On June 6, 2010, the world premiere of "Heartsongs" took place at Carnegie Hall, NY, featuring Mattie's message and poetry set to music by composer Joseph Martin, and performed by a 200 voice combined Children's Choir (many of them from Houston)and other members of the Distinguished Concerts Singers International under the direction of conductor Stephen Roddy. The event was such an overwhelming success that a repeat performance has been planned for June, 2011 at NY's Lincoln Center, and plans are being made for a CD.

In 2010, the citizens of Lapeer, Michigan will celebrate their fifth annual "World Trade Day" on September 11. (Mattie Stepanek described his vision for "World Trade Day" in his book "Just Peace", as a way of commemorating the tragic events of 9/11 while moving forward.)[citation needed]
