Vocalist/harmonica player Big George Jackson was born November 16, 1949 and in the Twin Cities he is known as the authentic big man of the blues. He sings with a distinctive bass-rich voice only a six-foot, six inch gentle giant could be blessed with. Add his fat harmonica playing, dead-on phrasing, commanding stage-presence and instant audience rapport and it's easy to understand why the audience howl when he delivers his music.
