Andre Virgin, professionally known as Doktor and formerly as Doctor, is a British singer and MC from South East London whose music spans a broad range of dance music and soundsystem genres.

Known for a spell of time as a grime MC, Doctor is a blood relative of Drastic and the Mastermind Trooperz members Lioness, Bear Man and Mista D. While leading the crew South Agents, he had a street hit with the D-Power Diesle and Riko Dan collaboration “C'mon” in 2005 and released a debut mixtape, Before Surgery, the same year.

The D.O.C’s first significant dance music hit was a feature on Soundbwoy Ent’s “Never Gonna Say” in 2006. He now creates EDM, dancehall and hip hop, with a vast discography in dubstep and drum and bass as a featured artist. Past collaborators include Chase & Status, Sigma and Flux Pavilion.
