Fred Keller, singer, mandolinist and songwriter has created a CD and book, each called Drifting Down the Kettle River, which happens to flow by Fred’s home in northern Minnesota. These projects illuminate Minnesota history and lifestyles over time. Fred’s trio is called The Skally Line, and after a rehearsal, band members talked about Drifting Down the Kettle with Phil Nusbaum. When they got together, Fred addressed why he composes songs about Minnesota history.
