Matthew Coley presents on the fantastic stories of our marimba history, concentrating on Iowa's contribution between the 1930s and 1950s! He will perform on a marimba that was owned by an Iowa player in the 1940s and coincidentally, was donated to Heartland Marimba in 2025 by way of PA. The presentation will include beautiful images and video from the period.

Free and open to the public. Please consider donating to Heartland Marimba, a 501(c)(3) nonprofit organization.
