Keller & Ella Williams
Keller and his daughter, Ella Williams, first collaborated when she was just 5 years old and he bribed her with candy to sing on his 2010 KIDS album. In 2018, at age 13, he bribed her with money to join him for a set on the Floyd Fest Children’s Universe stage and she has joined him every year since. He is just recently able to perform with Ella without crying.
