[1] Although he was an esteemed musician, composer, and teacher, Hustad's richest legacy resides in his informed criticism of evangelical church music and his well-developed philosophy of worship communicated through lectures, articles, and books.
His formal music training began with piano lessons at the age of four, and when he was eight he was playing gospel hymns in public worship and providing improvised accompaniments for the institution's Christian radio station.
His later desire to construct a philosophy of church music that could withstand the rigors of liturgical and musicological debate stemmed from both his theological study and his interest in logical discourse.
Hustad’s life was woven from these varied strands—a fragmented family unit, a conservative theological atmosphere, diverse musical styles, and learning opportunities afford by school, church, and local courtroom.
Hustad’s musical skills provided the financial support needed during his undergraduate education at John Fletcher College near Oskaloosa, Iowa.
In addition to directing the college band and leading a male quartet, he taught himself basic organ technique and became organist at First Methodist Church in Oskaloosa during his last year of school.
"[3] Hustad performed with featured soloist George Beverly Shea on Club Time, a program of hymns that aired weekly on the American Broadcasting Company radio network.
Hustad's transition from Director of Music at MBI to full-time organist with the Billy Graham Evangelistic Association allowed him to complete his doctorate in 1963.
His six years in this role also gave Hustad the opportunity to perform on outstanding instruments around the globe,[6] conduct workshops, give lectures, prepare articles for publication, and create a network of friends and associates.
Hustad held the position of chief editorial consultant with Hope from 1950 to 1961, although his counsel as a musical advisor for the firm continued for three more decades.
He received an honorary doctorate from Samford University in 2006,[11] and in March, 2008, Hustad was honored at the American Choral Director's Association's Southern Division Conference for his contributions to church music.
