Dr. Octagonecologyst

Dr. Octagonecologyst is the debut solo album by the American rapper and Ultramagnetic MCs member Kool Keith, using the alias Dr. Octagon. It was released through Bulk Recordings in April 1996. A release in the United Kingdom through Mo' Wax followed in May the same year. The album was reissued with a different track listing by DreamWorks Records in 1997. The album was produced by Dan "the Automator" Nakamura and featured the work of turntablist DJ Qbert. KutMasta Kurt provided additional production work. The cover artwork was drawn by Brian "Pushead" Schroeder.

Dr. Octagonecologyst introduces the character of Dr. Octagon, a homicidal, extraterrestrial, time-traveling gynecologist and surgeon. The album's distinctive sound fuses genres such as psychedelic music, trip hop, and electronic music. Thornton's lyrics are often abstract, absurd, and avant-garde, drawing on surrealism, non sequiturs, hallucinatory psychedelia, and themes of horror, science fiction, as well as sexual humor, absurdist/surrealistic humor, and juvenile humor.

Kool Keith's lyrics and Nakamura's production were highly praised, as was DJ Qbert's innovative scratching. The album has been ranked as one of the best hip-hop albums of the 1990s. The character of Dr. Octagon has also appeared in Kool Keith projects like First Come, First Served (1999) and Dr. Dooom 2 (2008), both of which contain tracks in which Octagon is murdered by Dr. Dooom.
