Artist development is a sustained, marketing-driven commitment to the long-term success of an artist or band.
Good artist development seeks to build and maintain a dedicated fanbase for the artist by all means necessary. The goal is to help artists reach as many people as possible, using the limited budgets available to put together effective marketing and publicity campaigns, among other things.
But true artist development is more than that. It encompasses everything that needs to happen to make sure that an artist or band is successful for the long-term.
It starts with marketing and publicity, but can encompass radio promotions, live performance, material selection, recording, web development...there are as many different formulas for success as there are bands - good artist development helps identify anything that may hold the artist back, and works to eliminate those obstacles.
