He began writing, recording, and performing at the age of 17. In his late twenties Curran began posting his videos on YouTube, and soon built a strong following on the strength of singles/videos like "Motivation" and "I Will Never Stop." In April 2016 he issued his first collection of music.
Curran donated 50 percent of the profits from I'm Not a Rapper to the LDS missionary fund. Although he doesn't make religious music, he believes in being open and true to who you are hence the moniker James The Mormon. "Mormon" is a nickname for a member of The Church of Jesus Christ of Latter-day Saints.
