Answer by taking a quote from the following article:

Guttermouth is an American punk rock band formed in 1988 in Huntington Beach, California and currently recording for Rude Records/Bird Attack Records. They have released nine full-length studio albums and two live albums and have toured extensively, including performances on the Vans Warped Tour. They are infamous for their outrageous lyrics and behavior which are deliberately explicit, offensive and intended to shock, though usually in a humorous and sarcastic manner. This behavior has sometimes resulted in high-profile problems for the band, such as being banned from performing in Canada for eighteen months and leaving the 2004 Warped Tour amidst controversy over their political views and attitudes towards other performers.

By 1994 Full Length had been available for almost four years and the members of Guttermouth were preparing to write a second album. They originally considered releasing the album themselves, but were soon approached with an offer from Offspring singer Dexter Holland, who in the wake of his own band's success was starting an independent record label and wanted to put out Guttermouth's next album as his first release. They agreed and recorded the album Friendly People as the first release on Holland's new label Nitro Records, and filmed an independent music video for the song "End on 9." Guttermouth would remain with Nitro over the next five years, releasing an album each year on the label.  1994 also found the band playing to a much larger audience. The success that year of The Offspring's album Smash and Green Day's Dookie had brought the southern California punk rock scene into the national spotlight. Thanks to their friendship with The Offspring and their new record deal with Nitro, Guttermouth found themselves embarking on their first national and world tours opening for larger punk bands. However, their typically outrageous behavior would often find them at odds with the other bands, audiences, and venues at which they played. After about six months of touring with this reputation the band found themselves banned from performing in numerous cities and clubs and blacklisted by many of the bands with whom they had hoped to tour. To the band, however, this behavior was typical and in keeping with the anarchic ideals that were at the core of the punk movement.  At one point the band found themselves ejected from a tour while in South Carolina, where they booked themselves at a club and recorded a performance which would later be released as Live From the Pharmacy. Adkins was arrested and briefly jailed in 1995 on charges of inciting a riot during a Guttermouth show at the Glen Helen Blockbuster Pavilion in San Bernardino, but evidence was insufficient to file charges.

Who did they owe this too
