Did you know that one of the chief architects of Motown’s funk-soul sound plays at Northern Lights every Tuesday, and it’s free? The 75-year-old guitarist burns it up every single week. We all have the easiest access to the once and future Funk Brother who blazed through “Ball of Confusion,” “Psychedelic Shack,” and “War,” not to mention his own hits like the stellar instrumental “Scorpio” (or his playing on Rodriguez’s Cold Fact). You can see him every Tuesday; why not show up this very night? You won’t be sorry you went.
