A 2010 video buried deep on the internet shows rapper Eddiedition lighting up a makeshift stage at the old Twins Bar in the Duluth Hillside. It’s a smoking performance of “Do Ya Thing” and evidence that Eddie Higgins, who’s been MCing as Eddiedition for nearly 20 years, is a Twin Ports hip-hop institution. Higgins has worked for years with local artists like Jaze, Bliss, Legitimit, C-Silence, Adub and Nonfic — and for causes such as Toys for Tots and breast cancer awareness.
