As I was doing my homework for writing a preview of NXNE, I noticed that several of the artists on the schedule were classified by genre as "Indie" or "Indie Rock". I've seen the question raised in other places--is "Indie" really a genre? What does it mean? And if it isn't a genre, and refers only to record label status...what does it mean? It's become kind of an ambiguous term. What do you think of when you hear the term "Indie?"
