So, as I mentioned, I've spent a lot of time in the past year or so learning about the Columbus music scene. Here's a list I made of a couple of my favorite artists with roots of some sort in Columbus. Several of them have since moved on to New York or California, but they still have some connections still here.
There are many others that I'll add to the list as time goes by, but I'll stand by this for now.
P.S. if you like this list, please feel free (i.e. please do) rate it highly on the iTunes Store. KTHXBAI
