Although they were raised 100 miles apart, (Kathy in the city of St. Paul, MN and Tim on a dairy farm in rural Cadott, WI), they grew up listening to the same music.  Being inspired by the songs of Peter, Paul & Mary, Simon and Garfunkel, and The Everly Brothers, it was very natural for them to sing the same type of harmonies when they began performing together in college.  As the duo grew musically, they also grew romantically and were married shortly after graduation from UW-River Falls in 1981. After singing as a duo for 15 years, their children Casey and Joe began making an appearance with them on occasion.  The duo became a quartet and played as a foursome for the next 10 years.  In recent years, with Casey and Joe both married with families of their own, Tim and Kathy most often play as a duo.  However, Danville continues to perform in every possible combination of members, which sometimes may also include nieces Hannah Bakke and Elizabeth Kulus.

Whether playing at concert halls, coffeehouses, churches, or music festivals, they move audiences from tears to laughter with songs and stories about love, family, children, memories, and relationships.  They call their style of music "acoustic contemporary folk" and have recorded six CDs: Love Like a River, Age to Age and Heart to Heart, a Christmas album entitled A Danielson Family Christmas, Casey and Joe's two CDs, Casey and Joe Live and Cornerstones and Commontime, and Tim's solo album A Place I Know.

In addition to being part of the folk music scene, Tim and Kathy perform with another group of area musicians "The Swampers." They can also be seen on stage with the local community theater "The Wayward Players."  Every now and then Tim and his siblings perform as "The Danielson Brothers."

Danville has enjoyed playing for audiences young and old, large or small, for over 40 years and will continue to do so as long as folks continue to listen.
