NACUSA was founded by Henry Hadley in 1933 as the National Association of Composers and Conductors. It is one of the oldest organizations devoted to the promotion and performance of music by Americans. Many of the most distinguished composers of the 20th Century have been among its members. NACUSA sponsors several concerts each year that feature music by its members. NACUSA has chapters in the Mid-South region, East Coast, Los Angeles, San Francisco, Missouri/Kansas, Southeast region, Texas, the Mid-Atlantic region, Cascadia, and Southern Oregon.
The objectives of the Mid-South Chapter of NACUSA are designed to promote music of composers in the Mid-South region of the United States. The chapter sponsors several concerts annually which feature various guest ensembles, soloist, lectures, and multi-media presentations. The chapter is currently based in Baton Rouge, Louisiana and provides compositional opportunities for local members as well as members outside the region. Since its creation in 1995 by founding members Al Benner, Dinos Constantinides, Mikel LeDee, Wallace McKenzie, Wieslaw Rentowski, and Mickie Willis, the Mid-South Chapter of NACUSA has presented numerous concert performances around the Baton Rouge and surrounding area including The Baton Rouge Art Gallery, Louisiana State University, Southeastern Louisiana University, and the LSU International Cultural Center.
