McDonald organizes and makes available information on music appropriate for concerts performed by a symphony orchestra, school music department, church choir, or solo performer in celebration of Martin Luther King Day or Black History Month. His selections include not only music written specifically in honor of King but also about other Americans associated with the struggle for equality and freedom, such as Abraham Lincoln, Malcolm X, Harriet Tubman, Frederick Douglass, and John F. Kennedy. He also includes works dealing with African American history and culture, such as William Grant Still's Afro-American Symphony. The third edition includes a considerable number of revisions and updates, with many new works added. Additions include an entirely new section devoted to jazz and blues songs, an overview of Martin Luther King Day concerts with sample programs, and a discography, along with appendixes of works listed by orchestration, subject, and a list of publishers and sources.
