Heavy metal has long been associated with dark, evil and nefarious themes. Throughout its history, metal has also been linked with rebellion and the questioning of authority. While the stigma has by and large been accurate in the past, an underground movement has been gaining popularity over the last decade.There have long been fringe Christian metal bands with product available exclusively in Christian outlets and gift shops. For the first time, extreme Christian music has moved from the dusty back bins of the Christian bookstores to the front racks at super retailers like Best Buy, Wal-Mart, Target and Hot Topic. Every day these bands are on the road traversing the country and taking their message and their brand of music to the masses hoping to make a difference. "Metal Missionaries" contains in-depth interviews with over 20 groundbreaking extreme Christian artists from around the globe, including BECOMING THE ARCHETYPE, CORPUS CHRISTI, GRAVE ROBBER, FEARSCAPE and many more. Beginning April 1, "Metal Missionaries" will be available for digital download exclusively through www.undark.net.
