The band were officially formed in 1997 as a reaction to what was an apparent commercialization of the punk genre. Their first demo was released in 1998 and their first official release came in 1999 when newly founded indie label Geykido Comet Records released the band’s song Education as a limited edition 7” vinyl.
In 2002 the band signed to Anti-Flag’s label A-F Records which released their self-titled full length album in spring 2003.
In June 2007 Intro5pect toured the United Kingdom and Mainland Europe. Around this time the band’s new demo ‘War At Home’ was spot-played several times by BBC Radio 1 DJ Mike Davies on his Punk Rock show ‘The Lockup’.
On October 16, 2007, the EP Realpolitik was released, featuring Stza from Leftöver Crack on vocals.
In Summer 2008 the band embarked on their second tour of the United Kingdom and this time played several headline shows at such venues as the Camden Underworld. Further support came from Mike Davies who this time had the band in to do a live session at the World Famous Maida Vale Studios. The show was broadcast the following week on BBC Radio 1.
Upon returning home from this tour, the band and bassist Gregg parted ways due to creative differences. After an extensive search Landon Hell was drafted in to fill the void.
