Interview: Tessa Johnson on Nashville's music scene

• What draws a Christian musician to Nashville?

Guest Tessa Johnson explains why she moved to Nashville: acceptance at a worship school with scholarships she felt she didn't deserve, and the pull of a collaborative musician community. She describes the intimidating hipster coffee-shop culture, how hard it is to book paying gigs without a label or following, networking-by-chance (a friend's video tweeted by Taylor Swift), and the unwritten Nashville rule against approaching celebrities — illustrated by her star-struck Gavin DeGraw sighting. The hosts riff on how they'd embarrassingly try to evangelize celebrities.
