After being named best unsigned artist of 2002 by Toronto's Now magazine and earning an industry buzz for his hip-hop shows dubbed D-Siggy's Playhouse, rapper D-Sisive dropped out of sight. But now he's represented by Los Angeles-based Core Entertainment. D-Sisive, whose real name is Derek Christoff, was born in Toronto, Canada and first started performing at age 16 in 1996. He dropped his first independent EP, "J.A.C." in 1997, including the debut single, "Lost Sight," featuring Toronto MC Abdominal. The following year, he began working with Issacs, eventually signing to his Bassmint Productions (now Moca Music).
