Their early lineup consisted of Don Chaffer as well as bassist Anthony Case, keyboardist Jay Pfeifer, and drummer Brandon Graves.
Chaffer's wife, singer/guitarist Lori Coscia, joined Waterdeep in 1996, with the group's second album Sink or Swim appearing the following year.
Meanwhile, the line up changed, with Kenny Carter on bass and Brandon Graves' wife, Christena, on keyboards.
They continued making records as solo artists and as the band Waterdeep, but first they embarked on a two CD series for a book project called The Voice.
Some of the artists involved (either writing or performing) were: Matt Wertz, Stephen Mason, Sara Groves, Derek Webb, Sandra McCracken, Steven Delopoulos, Matthew Perryman Jones, Robbie Seay, Andrew Osenga and Phil Keaggy.
It was a mix of folk and techno, and the back story caught the attention of Steve Day, a fan in New York City who thought it would make a great musical.
Don, up for the challenge, ended up writing it with Chris Cragin Day and solicited the help of Lori to finish up some of the songs.
