Accordion duo Brent Buswell and Burt Stromholm, along with Crista Buswell on piano, will perform a free concert at 7 p.m. Wednesday, July 2, at the Marquette Commons.

The event is presented by the Beaumier Heritage Center at Northern Michigan University and the Finn Grand Fest Foundation. Buswell has been blind from birth and began playing the piano when he was three years old. He received his first full-size accordion at age 12 and it became his main instrument. He also plays the organ and percussion. Buswell graduated from Berklee College of Music. He has released three albums and performed with the Grammy Award-winning Jimmy Sturr Orchestra and at the Finnish Embassy in Washington, D.C. He has also appeared at many functions across the country, including Finn Grand Fest 2005 in Marquette. Stromholm has performed and played dances on the accordion since his youth, either as a solo act or as a member of various bands. He has also written shows and has been actively involved in organizing Scandinavian events and hosting performers from Finland and the United States. The duo has played together for more than 10 years and boast a diverse repertoire of music: classical, American standards, Christian, Scandinavian and more.
