From the Mars Hill Church resource website:
Artists are like ants. Ant / artist colonies send out scouts to scope out new territory and report back their findings. If you squash the scouts or have nothing for them to sink their teeth into, they move on. Identify and create opportunities in your church for musicians. If your church has no platform for artists to grow, create, and contribute, then don’t expect them to stick around. Music is not the purpose of the church, but it can be immeasurably effective in communicating the message that is the purpose of the church, as evidenced by both the word of God and church history.
It’s essential to appoint someone who can be leader and liaison to musicians in your community. When selecting a leader over musicians, pick someone who understands the gospel, artistry, and the specific calling of your local church. Musicians should be held to the same standards as other leaders, but know they typically have their own culture—including language, behaviors, motivators, strengths, and weaknesses.
