Fronted by Jeff Harder and Keith Wallace who sets a passion and flair that has never existed known to man. Putting the rhythm to your neighborhood is Jon Kabir on bass that flips and wails like a demented psychopath that lies behind his dark eyes and black hair. Moving quickly up the ranks of opening acts to headlining band, in the beginning of the year 2005 SIGMA was described as “ The Hardest Working punk band in Arizona.
