"The Wild Inside" (2014) featured Michael Ketterer and was released under the brand "Michael Ketterer and United Pursuit". United Pursuit is also known for their weekly Tuesday gatherings from which many of their songs were written. These gatherings were birthed in a residence on Banks Ave in a North Knoxville neighborhood. This residence is commonly referred to now as the Banks House. Over the course of several years, these gatherings have grown in number, pushing United Pursuit and others out of the Banks House and into, at one point, a larger living room and eventually other commercial and public spaces. After much transition, United Pursuit's Tuesday gatherings found a home at a renovated commercial space near downtown Knoxville. This space, now commonly referred to as the Fifth Avenue House, continues to grow as a commercial space and currently caters to both United Pursuit and independent events such as wedding, concerts, etc... The music released and the Tuesday gatherings held by United Pursuit over the years has been the product of their humble beginning with a simple desire to commune with God and each other. The name United Pursuit is in itself reflective of the heart of the United Pursuit community, "doing life together as we seek God through both song and relationship with others".
