Since 2003, SIGMA have performed many shows both local and nationwide. Producing the unique blend in sounds of punk-metal, channeled by an unforgettable member switch in lead vocals/guitars and drums. Two shows/performances in one band. 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 band in Arizona” by . Sigma has shared stages with many of today’s well known and hottest bands as well as with legendary performers who have been a big influence on the band such as Conflict, River City Rebels, Total Chaos, Though Riot, Pipedown, The Code, The Soviettes, Antifreeze, Killradio, A Wilhelm Scream, Lower Class Brats, The Fight, Destruction Made Simple, Lostprophets, The Adolescents, Michale Graves, Narcoleptic Youth, 2005 Vans Warped Tour and the list goes on.

SIGMA will unleash their arsenal of punk metal riffs and carefully crafted thought-provoking lyrics on society with their second full-length album release in 2006. SIGMA has a new level of determination and will be one of the bands to watch out for in 2006.
