The Crimson House Blues Band having been going for, I think, about 7 years and I always get the chills when watching them live. They were a regular house band when The Blues Sessions in Cape Town convened. Starting off as a 4 piece they have grown adding brass, violins and other interesting instruments and great voices, all the time. They really have a vibe that whenever they play, your feet seem to get infected by their rhythym. Enjoy the below video:
The first time my girlfriend heard them, I almost lost her to Riaan, the leadman. Actually I cannot blame her. They really get you going.
