As the group Hustlers Convention, Jon Pearn and Michael Gray produced their own house tracks and remixed many others, including "Street life" by C. J. Lewis and "Got Myself Together" by the Bucketheads. Their first release was The Groovers delight EP in 1992 on Stress Records.
They have appeared in the US Hot Dance Music/Club Play chart three times with their own singles, first under the name Arizona feat. Zeitia with "Slide on the Rhythm", which reached number one in 1993, and with "America (I Love America)" under the Full Intention name, a number one hit from 1996. They are also perhaps most well known for their remix of the 1995 club classic "So In Love" by Duke.
In 1997, they released a song as the act Sex-O-Sonique called "I thought it was you", which went to number one in the 1997 UK dance singles chart on 6 December, pushing The Prodigy "Smack my bitch up" off the top spot.
Although many of their remixes for other artists have been successful club hits, they did not return to the chart as artists until 2002, when "I'll Be Waiting" featuring Shena reached number three[where?]. Both members have achieved solo success with Gray releasing singles "The Weekend" and "Borderline" which were club hits, while Pearn has formed a side project Bodyrox.
In 2009, Jon Pearn and Michael Gray released new versions of the singles "Once In A Lifetime", "I Will Follow", "Forever" under the label Full Intention Records. In 2010, they released a single entitled "America 2010", remixing their own famous 1996's song. In the late 2010s, the most popular singles of Full Intention were "Keep Pushing" (2016) and "I Miss You" (2017). In 2018, they released a single with Blaze called "Be Yourself".
Full Intention has also released a number of remixes. They released in 2018 a remix of a David Penn song with Lisa Millett entitled "Join Us". They have notably released remixes of classic house tracks like Inner City "Big Fun", Frankie Knuckles "Tears", or Black Riot "A Day In The Life".
