Deric Michael Angelettie, also known by his stage names D-Dot, Papa Dot, and the Madd Rapper, is an American record producer. He served as executive producer and A&R for the album No Way Out by Puff Daddy & the Family, which won a Grammy Award. He has since done so for three other albums nominated for the award, and won the BMI Urban Award in 2001.
While attending Howard University in the late 1980s, Angelettie and Ron "Amen-Ra" Lawrence formed the hip hop duo Two Kings In A Cipher, and signed with RCA Records to release their debut album, From Pyramids to Projects. He joined Bad Boy Records' production team the Hitmen by 1995, after which he was credited on releases for artists including the Notorious B.I.G., Jay-Z, and Mary J. Blige, among others. He served as the team's de facto "Captain" by the time he produced the label's 1997 singles "Hypnotize" by Notorious B.I.G. and "It's All About The Benjamins" by Diddy.
As a recording artist, he created the alter ego, The Madd Rapper, to guest perform on B.I.G.'s second album, Life After Death.
