DJ Marfox — the stage name of Marlon Silva — is best known for pioneering a new music genre that emerged from the Portuguese capital’s housing estates, referred to as ghetto sound of Lisbon, "batida" or "batucada",[2] which incorporates African-influenced dance music such as kuduro, kizomba, funaná and tarraxinha with house and techno.

His stage name combines the first syllable of Marlon with the name of the character featured in the Nintendo game Star Fox he used to play as a teenager.

Born on June 1988, in Lisbon, Portugal of São Tomé e Príncipe’s parents, DJ Marfox started deejaying in 2002.

In 2005, together with DJ Pausas and DJ Fofuxo he founded DJs Do Guetto[8] and a year later they released DJs do Ghetto Vol. I a digital compilation made up of 37 tracks onto eMule. This compilation, which has since been re-issued as a free download by Príncipe Discos, has been viewed as the foundational release of the ghetto sound of Lisbon.

His first solo album, Eu Sei Quem Sou (I know who I am), released by Príncipe Discos in early 2011 was described by Philip Sherburne as “an atomic field of taut drums and hiccupping yelps and zapping synths and pinprick details."

In 2014, DJ Marfox released an EP called Lucky Punch on Lit City Trax and went on to perform in the Red Bull Music Academy in New York as well as in the Warm Up — the live music concerts curated by MoMA PS1. According to Cedar Pasori, DJ Marfox's participation in MoMA PS1’s highly acclaimed experimental electronic music series, which took place on August 30, 2014, “reinforced the accelerating spread of Afro-Portuguese dance music around the world.” The album Lucky Punch was listed as one of DAZED’s top ten albums for August 2014. In between the aforementioned performances, the Rolling Stone magazine included him in their list of “10 New Artists You Need to Know”.

One of the first international collaborations of the Portuguese DJ and producer was a rework of tUnE-yArDs’ song Water Fountain featuring Brazilian band Pearls Negras.

On March 13, 2015 the British independent record label WARP announced the release on April 7th of a new EP called Cargaa 1 featuring DJ Marfox as the central figure of what MR P describes as the “cream-of-the-crop purveyors of Lisbon’s thrilling electronic dance scene”.

A compilation of songs crafted in the artist’s bedroom from 2005 to 2008 was launched as a CD as well as free download under the name Revolução 2005-2008 on March 16, 2015.
