The AM:PM years
After working in A&R at Cooltempo, Dunmore joined AM:PM, the UK dance division of A&M Records, where he worked from 1994 to 1998. The label had major club-to-chart hits in that time, including Ultra Naté’s Free, Mousse T’s Horny and MJ Cole’s Sincere.
Founding Defected Records
In January 1999 he launched Defected in London with initial funding from Ministry of Sound. The very first release, Soulsearcher’s I Can’t Get Enough, went to No.5 in the UK. Hits followed fast:
- Roger Sanchez, Another Chance: UK No.1 in 2001
- Kings of Tomorrow, Finally (2002)
- Shakedown, At Night: UK No.6
- Bob Sinclar, Love Generation (2005)
- CamelPhat and Elderbrook, Cola (2017): Grammy-nominated and platinum in the UK
- Endor, Pump It Up!: UK No.8 in 2019
Glitterbox, Croatia and Ibiza
Dunmore came up with Glitterbox in 2014, a disco and house party that started at Space Ibiza and moved to Hï Ibiza in 2017. Defected Croatia has run every August since 2016 at the Garden Resort in Tisno. In Ibiza, Defected has held residencies at Pacha, Eden and Ushuaïa. The label now runs around 30 sub-labels, including Glitterbox Recordings, Soul Heaven, Faith and Sondela.
Stepping back
In 2022 managing director Wez Saunders led a management buyout of Defected, and Simon Dunmore stepped down as CEO. He stayed on as an A&R consultant. By then the label was expecting billions of streams a year, hundreds of events and more than 600,000 tickets sold.
Why he matters
Few people have shaped modern house music as much. His ear for songs, his loyalty to vocal and soulful house, and his talent for building a brand that DJs, producers and clubbers trust turned a London label into a global community.
