Blake Dragon is a musician who performs traditional heavy metal music at religious services throughout the galaxy. His music is a mixture of many different religious traditions. As a theist tending toward a judeo-christian bent Dragon imbibes much of his art with references to themes of sin and redemption.
For the sake of the 21st century reader Blake is not an evangelist. Rather he sees himself more as a facilitator of religious experiences. For example, some Vulcans attend his services not so much because of the messages in his music but rather in order to train themselves in greater mental discipline in a noisy world.
One notable fan of Blake's work is Jan Droogendyk.
