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 the ghetto sound of Lisbon, "batida" or "batucada", which incorporates African-influenced dance music such as kuduro, kizomba, funaná and tarraxinha with house and techno.

In 2005, together with DJ Pausas and DJ Fofuxo he founded DJs Do Guetto 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. Lucky Punch was listed as one of DAZED’s top ten albums for August 2014 and the Rolling Stone magazine included him in their list of “10 New Artists You Need to Know”.

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