Pressure 4-5 was an alternative rock group hailing from Santa Barbara, California. The band broke up upon many of the band members leaving for alternate lifestyles not relating to music. Formed in January 1998 by vocalist Adam Rich (Now a Chemistry Teacher) and guitarist Mark Barry, Pressure 4-5 started simply enough, as two college friends forming a band together. Things quickly picked up when another friend from college, Lyle McKeany, joined the group as bassist. Joe Schmidt later joined the band as DJ before switching to rhythm guitar.
