I was just there last week for "Mad Agnes." They were PHENOMENAL. Probably the best Folk Musicians I've ever seen - and I've seen a lot. The snacks were awesome too. The best $10 I've ever spent for a 2 hour concert. They had problems with the audio and in true professional form they just ran with it. Rearrangeing their line up and doing accapella pieces while the tech crew fixed stuff.
My only complaint was that the gentleman who did the introductions was really long winded. I got to the point were I was getting antsy for him to shut up already and let us listen to the music. While it certainly wasn't the musicians' fault, he detracted from the overall experience. Oy.
