Danbury solo Peter Herger began songwriting since law school, but only in the past month or so, has his music career taken off to a place he never expected. The 30-year-old’s first music video, “A Train,” has become a YouTube sensation, getting more than one million hits. Also, his music is now being played on rock station, I-95, WRKI-FM in Brookfield.

“It’s really hard these days to break into FM rock radio,” Herger said.
