Alex Marusyk, left, and Ross Kircher had a creative jam session while playing Justin Timberlake’s “Cry Me a River” yesterday evening during an open mic night for 14- to 19-year-olds at the Fort Frances Public Library. The fourth open mic to date, it also was held as a fundraiser for the library. More will be held in the future since they are a great way to meet new musicians and get introduced to the local underground talent.
