Though just 22 years old, Minnesota singer/songwriter John Mark Nelson has already released four full-length recording projects. His 2011 debut, "Still Here," was released independently while Nelson was still in high school. Four years later, a fourth CD, "I'm Not Afraid," was released to critical acclaim. The album took on an entirely different approach as Nelson explains in this week's program. Nelson's work has caught the attention of many satisfied critics and he has appeared on public broadcasting favorites like World Cafe and Mountain Stage. John Mark Nelson played The Garage in Rapid City on May 25. He was joined on stage by Kara Laudon, Steve Bosmans, Josh Fink and Gabe Hagen.
