I only just discovered Erika Wennerstrom one month ago via Heartless Bastards on a re-aired episode of Austin City Limits on PBS. I was a bit mesmerized right away and knew I had to hear more. I'm low-tech and still prefer to buy CD's of a favorite artist. For me, Sweet Unknown is absolutely PHENOMENAL. I Cannot Stop Listening to it. Anyone who doesn’t experience it is really missing out.
