Ultimatum were a recognized name in heavy metal circles for well over two decades. Formed in 1992 in Albuquerque, New Mexico by guitarist Robert Gutierrez, the band has released several albums and performed across the U.S. Initially, they were named as "Holy Sacrifice", though they quickly changed their name to Ultimatum. The band’s style is a blend of traditional heavy metal, speed and thrash metal.
