Austin City LimitsOther than word of mouth (from social media sites like this one and others), I regularly go to Austin City Limits to see who is coming up on the show. They do a good job of "teasing" or promoting the upcoming artists and I've found some really nice gems on the show over the years. Bands I may have heard of, but haven't had a chance to hear - especially in a live setting. Of late, I've really enjoyed Civil Wars - incredible voices. Punch Brothers were on that same show - also hit a nerve with me.
Again, some of these groups may have been around awhile, but they are new to me!
