The 4th Normal Form Band (4NF Band) is a band from Franklin, IN that consists of four boys (ages 17, 16, 14, and 12) and their father. They began performing in public in January of 2002, after spontaneously forming in the Fall of 2001. They have performed regularly ever since. The 4NF Band has performed at venues ranging from coffee shops and churches to college campuses, festivals, conferences centers, and county and state fairs. The band has been seen by as many as 30,000 people at a single event (The Indianapolis Life 500 Mini Marathon). Because of the band’s unique make-up and musical talent, they are regularly invited to perform around Indiana and surrounding states. During the summer of 2010, the band performed 25 times in Taiwan (Republic of China).

The 4NF Band plays a variety of musical styles, including progressive, hard, and soft rock, as well as blues and new country. In addition to their own original music, they have covered such bands as Kansas, Journey, Jimmy Buffett, Boston, Rush, John Denver, Creed, and Kenny Wayne Sheppard. Their music can be found on their 5 full-length CDs, Seeds of Time, Here in America…, Mothers of Invention, HumaNature, and coram Deo. Various themes run through the band’s original works. Some of their material is philosophical in nature, while some is simply amusing—creative illustrations of contemporary life and thought.

The four boys are naturally talented musicians who have chosen their own instruments and roles within the band. Zach, the oldest at age 17, plays bass and sings background vocals. Isaac, who is 16, plays drums and sings lead and background vocals. Nathan, at age 14, plays keyboards and guitar and sings lead and background vocals and is the proud co-owner of a copyright for a song that appears on the band’s second CD. Elijah, age 12, is the band's percussionist, occasional keyboardist, and sings background vocals. And finally, Robert, father of the boys, is guitarist and sings lead and background vocals in the group. Although he played in various bands as a drummer and background vocalist the previous 30 plus years, he has now assumed the role of front man—much to the wonder of many of his ex-bandmates.

The boys are all taught by their father, although Nathan and Elijah also take piano lessons outside the home. In addition, they learn from watching others perform and from picking up ideas from friends of the family.
