Dem Bow is a song performed by Jamaican reggae singer Shabba Ranks, produced by Bobby Digital who helped popularize and spread the reggaeton in the 1990s, this song used Poco Man Jam riddim (based on the title track of Gregory Peck 1990) created by Jamaican producers Steely & Clevie in the late '80s and early '90s.
The musical foundation of the dembow beat is the infectious bangara, also known as the "Bam Bam its murder" riddim (1992). This rhythm was initially found in soca and then slowed down for reggae-dancehall on cuts like Chaka Demus and Pliers "Murder she wrote". Add to this beat throbbling sustained bass notes, synth parts that sound more hip hop then toasting on the chorus. The most popular songs performed over this rhythm was "Dem bow"(Shabba Ranks), "Murder she wrote"(Chaka Demus & Pliers), "Bam Bam" (Pliers), "Them a bleach"(Wardo Ranks) and "Rivers of Babylon"(Brent Dowe). The banga was initially played in the caribbean via soca and then slowed down for dancehall in 1992: the foundation for the dembow beat and later reggaeton music.
