Antony Genn joined Pulp in January 1988, taking over from Steven Havenhand on bass. He played with them until August of that year. Around that time he became involved with the Nine O'Clock Service. A Christian cult that incorporated elements of rave culture. He remained a member until 1995, when the church was closed down amid considerable media attention, following abuse allegations against its leader Chris Brain.
In 1995 he streaked on stage during Elastica's Glastonbury performance. After this, he played keyboards with Elastica for a few months while they were touring. He also became involved with Pulp again, receiving a credit for 'additional programming' on Different Class and helping out on guitar during some live dates in '96 and '97.
In 1999 Genn joined Joe Strummer's backing band, known as The Mescaleros, on guitar. He produced eight of the ten tracks on their first album called Rock Art And The X-Ray Style. He also co-wrote some of the tracks. He left the band in 2000.
Antony Genn currently fronts The Hours, a band that he formed in 2004 with good friend and fellow Mescalero Martin Slattery.
In 2007 he took part in a Premier League All Stars charity football match representing Manchester City. This was broadcast on Sky 1.
