Watermark got their start recording under the name Sons and Daughters, with longtime friends Charlie and Kimber Hall (Charlie Hall is a known worship leader with the Passion conferences). They released their first record, Holy Roar, with this lineup in 1995. In 1997, they released Open Me Up under the same name. That same year, Nathan and Christy Nockels began leading worship at Metro Bible Study at Houston's First Baptist Church. This is where Watermark began.

Rocketown heard about Watermark around 1998, and soon signed them to the label. That same year, they released their first project as a part of Rocketown, an album called Watermark. This disc is almost a complete re-record of the Sons and Daughters disc Open Me Up, with only a few song changes. Their second album, All Things New, which is probably their best-known project, released in 2000. Constant, their 3rd studio project with Rocketown, was released in 2002. Their final all-studio album, The Purest Place, was released in August of 2004. This project yielded the couple a GMA Music Awards nomination for Inspirational Album of the Year, and also helped to earn Christy a nod for Female Vocalist, though neither award was won.

On March 14, 2006, Watermark released their final album as a part of Rocketown. A Grateful People was recorded live at the couple's church in Brentwood, Tennessee in August of 2005. It includes 12 tracks from the 3-hour-long concert and 2 brand new studio tracks. Friends of the couple who have played roles in their ministry that are special guests on the album include Point of Grace, Chris Tomlin, Ed Cash, and Shane and Shane.

Throughout the years, Nathan and Christy have played a part in the Passion conferences, which were started by Louie Giglio. Most recently, Nathan has produced live recordings of the past 2 conferences in Nashville, TN (2005 and 2006).

Nathan is an avid producer, having produced not only the Passion CDs, but also Watermark's The Purest Place, and Rita Springer's I Have To Believe, among others.

Watermark has toured extensively during their career, doing both solo shows and also with such notable groups as Point of Grace and Michael W. Smith. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
