LaGrange International Friendship Exchange is sponsoring its second annual concert on Sept. 11 in honor of Marjorie Champion Salamone and Sgt. Corey Spates.

Salamone was killed in her Pentagon office on Sept. 11, 2001. Spates was killed by a roadside bomb in Iraq in February 2008.

The September concert began as a worldwide movement in 2002 as a way to promote peace and has grown to include 100 concerts in New York City alone last year, along with 46 U.S. cities and 33 international cities. Concerts held under the September Concert banner must follow three basic principles:

— All venues and musicians are free to organize their own concert in whichever way they feel appropriate;

— All music and musicians are treated equally, regardless of genre or background; and

— All music is offered free.

Last year’s event in LaGrange was a mix of local performers and visiting exchange students and international groups, including the New Heaven Baptist Korean Choir, Hugo Oropeza and Latino friends, and LaGrange High exchange student Xinyi Gao, performing on Chinese zither in Callaway Auditorium.

Ukranian exchange student Natalya Otsabryk, who also attended LaGrange High, and Angelyn Traylor, Miss Troup Teen performed, along with Re-Generation, Traci Jones, the Young Singers of La-Grange, Irish dancer Grace Oliver and others.

This year’s concert is at 7 p.m. Sept. 11 at Callaway Auditorium on the campus of LaGrange College.
