A folk singer from the old school, the St. Louis Park-reared singer troubadour is about building community, on- and offstage. For more than 40 years, he’s sung about struggling farmers, struggling workers, struggling veterans, underrepresented communities and the like. He has just donated his life’s work — recordings, oral histories, posters, personal writings, school workshops, etc. — to the University of Minnesota Libraries Performing Arts Archives. And Long continues to perform, with his ongoing American Roots Revue, this time featuring Barbara Cohen, Robert Robinson, Tonia Hughes Kendrick, Alana Dickenson-Gaabay Aniikwaad and a band led by Michael Bland and Billy Steele.
