Began DJing back in the early 90's and has had residencies at Pacha, Revolution and ACTV in Spain, The Play Room, Dolce and The Gardening Club in London and Mu Mu's in his hometown of Maidstone.
In 2005 Dave set up the independent dance music label Vines Vinyl Records purely for his own experimental hard house sounds, but quickly began signing more vocal based artists to the label.
The label has grown considerably in recent years with many artists signed and has now launched a sister label called VVR2 with a totally different direction away from dance music with the signing of many Britain's Got Talent finalists, indie rock bands, and commercial pop stars.
In September 2009, D'Mello signed Hollie Steel to his record label VVR2, where she began recording her debut single "Where Are You, Christmas?" from the American film Dr. Seuss' How the Grinch Stole Christmas. The single was released on 14 December 2009.
