Brother Danielson

When joined by his family the band is known as Danielson Famile or Danielson Family, whose members have included Smith; his "siblings Andrew, David, Megan, and Rachel; wife Elin; friends Christiaan & Melissa Palladino; [and] daughters Lilly and Ida". Sufjan Stevens has also recorded and performed with the group.
The band is known for Smith's squeaky, falsetto vocals, innovative musical arrangements, and matching uniforms "that act, according to Daniel, as 'visual reminders of the spiritual and emotional healing taking place' within audience members." During some performances Smith has "worn a nine-foot tall, hand-made nine-fruit tree to 'bear the good fruit,'" in reference to the fruit of the Holy Spirit.
