The bios of the musicians who make up the band Micah’s Rule read like many Christian artists. Grew up singing in the church. Preacher’s son. Then became a preacher. In many bands. Degrees in music and ministry. Recorded some albums. Toured with Christian music legends. Even struggled with their faith along the way. What their bios don’t mention outright might make them one of the rarest recent talents to record in Nashville, Tenn. The three musicians of Micah’s Rule are an openly gay man, transgender woman and a lesbian. But Greg McCaw, Chasity Scott and Mary Anne Hewett don’t want their sexuality to define them. They want their music to be the centerpiece of their life and ministry. “There are many people who are gay in the music industry in Nashville, but they’re so far in the closet,” McCaw said.
