Formed in 1999, the Pittsburgh, PA quartet, NEGATIVE 13 (once known as Negative Theory), has continued to have a bit of an identity crisis. Describing their sound as post-punk infested stoner/sludge/doomcore, NEGATIVE 13 carries a curiosity that has allowed the band to reform after a hiatus with a wide-open palette of taste that reflects their artistic vision: interpret their brand of heavy metal however it is they feel fit.
