Head over to the website for the Knoxville Tourism & Sport Corporation, which has a pretty straightforward events calendar at: http://www.knoxville.org/events/. Upcoming holiday events include things like a Christmas Market, regular First Friday art-gallery events, a Festival of Lights, and a New Year's Eve gathering on Market Square. You should also peruse the entertainment section of the Knoxville News Sentinel's website at: http://www.knoxnews.com/news/entertainment/ for more ideas.
