Longtime Charlotte singer/songwriter Si Kahn is known worldwide for his songs supporting labor rights -- some two dozen at least. This past year, he received the Joe Hill Lifetime Achievement Award from the Labor Heritage Foundation, a recognition shared by Cesar Chavez, Hazel Dickens, Pete Seeger, & Utah Phillips among others. He is also known for composing musical theatre ("Mother Jones in Heaven"), and collaborating recently with German bluegrass band The Looping Brothers. Si has a concert at Isis Restaurant & Music Hall in Asheville with Joe Jencks this Sunday evening. We welcome him to Studio B for a Monday morning session with Martin the next day.
