Roc Marciano, born Rahkeim Calief Meyer on February 11, 1978, in Long Island, New York, is an American rapper and record producer known for his intricate internal rhymes and wordplay detailing mafioso and pimp themes over sample-based production.

He has been called the "Godfather of the Underground" for pioneering the resurgence of gritty, lyrical rap and use of drumless sample loops in the early 2010s with his highly influential debut album Marcberg (2010).

Roc Marciano has released 10 studio albums and a variety of mixtapes and EPs, most of which are almost entirely produced by him. He frequently collaborates with underground artists such as Knowledge the Pirate, Ka, Action Bronson, Flee Lord, and various members of the Griselda collective while also producing for other artists.

Roc Marciano started his career in 1999 when he joined the Flipmode Squad and made his first appearances on "Whatcha Come Around Here For" and "The Heist". He left in 2001 to form the U.N., a hardcore underground hip hop group consisting of three other MCs (Dino Brave, Laku, and deceased member Mic Raw) with whom he released an album on Carson Daly's 456 Entertainment in 2004.

Roc Marciano appeared on the 2005 Wu-Tang Clan compilation album, Wu-Tang Meets the Indie Culture, and in Pete Rock's 2008 album, NY's Finest, drawing acclaim for such performances. Since 2008, Roc Marciano has been working on his solo career, and to widespread internet acclaim, released his entirely self-produced debut album, Marcberg, on May 4, 2010, to critical acclaim.

His lifestyle is marked by his dedication to his craft and his preference for working independently. He often sports a stylish yet understated look, embodying the best-case scenario for a rapper working outside the major label system.

His direct-to-consumer sales model has given many artists a roadmap to a sustainable career outside the major label bubble.

His career has been marked by his commitment to creating music on his own terms. His solo discography, especially albums like Marcberg, Rosebudd's Revenge, and Mt. Marci, are canonical exhibitions of storytelling and dense lyricism.

His albums move with a quiet intensity, layering hushed samples with heavy imagery to create a mood that's both gritty and hypnotic. His style is imitable; he rhymes with urgency and magnetism that's unmistakably New York, often delivering rewindable material in a distinctly off-kilter flow.

His songs are known for their dense lyricism and cinematic quality. Tracks like "Marcberg," "Reloaded," and "Rosebudd's Revenge" showcase his storytelling prowess and his ability to create vivid imagery with his words.

His collaborations with other artists, such as DJ Muggs and The Alchemist, have also been well-received, adding to his reputation as a versatile and talented producer. Roc Marciano has received critical acclaim for his work, although he has not won many formal awards.
