Daniel Alan Maman (born October 25, 1977), professionally known as the Alchemist (or simply Alchemist), is an American musician, record producer, DJ, rapper and songwriter. He began his music career in 1991 in the hip hop duo The Whooliganz under the moniker Mudfoot, along with now-actor Scott Caan (whose moniker was "Mad Skillz"). After rising to prominence in the late 1990s, as a close associate of Dilated Peoples and Mobb Deep, he went on to produce for many of hip hop's leading artists in the 2000s, and has been hailed as one of the genre's leading producers. While he produces for many artists, most of his recent production has been for a close group of frequent collaborative rappers. He focuses on producing entire albums for rappers and instrumental projects of his own. He is currently Eminem's official DJ.
Together with his longtime collaborator Oh No (with whom he forms the group Gangrene), Woody Jackson and Tangerine Dream, he composed the official score to the 2013 video game Grand Theft Auto V.
