Harold Armstrong, better known as DMG (short for DetriMental Ganxta), is a hardcore rapper formerly signed to Rap-a-Lot Records. He is known to many hip-hop critics for his overtly violent lyrics and having a sound and flow similar to his mentor Scarface.
DMG got his start in St. Paul, Minnesota recording underground hip-hop tapes in the early 1990′s. One night after a rap concert, DMG followed rapper Scarface to his hotel room where he played for him one of his tapes. The impressed Scarface took a liking to DMG’s unique style and landed him a deal with Rap-A-Lot Records where the Minnesota-based artist released the underground classic "Rigormortiz" in 1993.
Several years later, DMG was invited to become a part of Scarface‘s spin off project Facemob, a hip-hop collective consisting of several rappers from different regions. DMG continued recording on collaboration hip-hop projects for Rap-A-Lot into the late 1990′s and early 2000′s, including a second solo release titled "Black Roulette" in 2003.
