In 1999, the band released an independently released EP, entitled "Antechnology". They continued performing throughout California and, with the help of music websites and fanzines, quickly built a following. After a warm welcoming from the rock community and a large outpouring of support, Pressure 4-5 was quickly signed to DreamWorks Records in 2000, where they released their only full-length album, "Burning The Process", in autumn the following year. Amidst the alternative metal craze, 2001 would prove to be Pressure 4-5's most successful year; they acquired a spot on the Second Stage of Ozzfest 2001 before touring with groups like Dredg, The Used, and Lit. A live October performance in Colorado would also be taped for an MTV special in November. However, of the band's most memorable concert experiences include a sold-out show with Alien Ant Farm at WWF New York following the September 11 terrorist attacks. "Burning The Process" went on to sell 80,000 copies.
