Dr. Octagonecologyst is the debut solo studio album by American rapper and Ultramagnetic MCs member Kool Keith, released under the alias Dr.

Keith and producer KutMasta Kurt – who were working on a variety of demos together – recorded two songs called "Dr. Octagon" and "Technical Difficulties".

[7] Thornton mailed the songs to radio stations as well as giving copies to several DJs and record producer Dan the Automator.

[12] On the Bulk Recordings edition of the album, "halfsharkalligatorhalfman" is preceded by an excerpt from the comedy film Cabin Boy.

"[14] AllMusic reviewer Steve Huey wrote that the album "shed some light on the burgeoning turntablist revival via the scratching fireworks of DJ Q-Bert" and its "futuristic, horror-soundtrack production seemed to bridge the gap between hip-hop and the more electronic-oriented trip-hop".

[6] Music critic Chairman Mao wrote that Dr. Octagonecologyst occupies "...the heretofore-undefined area where hip-hop meets hallucinatory sci-fi and porn.

[16] "General Hospital," "A Visit to the Gynecologist," and "Elective Surgery" detail a list of services offered by Octagon, who claims to treat chimpanzee acne and moosebumps, and relocating saliva glands.

The Past, Present, and Future of America's Most-Wanted Music, "The album's beginning and ending tie together the stories of the fictional character Dr. Octagon and the rap career of Kool Keith Thornton himself: We begin with '3000' and end with '1977,' which purports to be an audio recording from an early rap performance by Kool Keith ... announcing a 1977 rap show featuring ... pioneers Grandmaster Flash, Kool Herc, the L Brothers, and the original scratch creator Grand Wizzard Theodore.

[19] The "Blue Flowers" maxi single featured the original vocal and instrumental versions, the vocal and instrumental versions of the "Automator Remix", the "Flower Bed Mix *2" by DJ Crystl, the "Secondary Diagnostic Mix" by Photek, and the DJ Hype remix.

[11] In the United States, the album was issued by Bulk Records on vinyl as a double LP,[32] and on compact disc with bonus tracks,.

[33] Separately, it was also issued by Mo' Wax in the UK as a triple LP and CD, reflecting the track listing of the Bulk Recordings compact disc.

[11] Dr. Octagonecologyst was re-released on triple vinyl in June 2017 by Geffen/UMe/Universal via Get on Down, which included the original album, unreleased tracks from the era, and remixes.

These performances were supposed to feature a full live band, an on-stage breakdancer, and appearances by Invisibl Skratch Piklz.

"[15] Chairman Mao of Rolling Stone remarked that "Kool Keith leads and oversees the chaos with a Zappa-esque commitment to decadence.

"[12] Alternative Press praised the album's "deep, dubby bass lines, spooky melodic riffs and consistently heavy beats",[24] while The New York Times called it "one of the most progressive rap projects to be released in the past year.

"[42] Melody Maker called it "bloody essential" and stated, "While commercial American hip hop is slithering into an insipid mire of soulless, identikit swingbeat, Dr. Octagon has made an album swathed in character [...] Get yer prescription fixed.

[25] Following initial reactions to the album, Dr. Octagonecologyst continued to earn praise from contemporary writers and music critics.

[30] PopMatters columnist Michael Frauenhofer called it "a landmark album of dope beats and mind-bending experimental flows.

[6] Allmusic reviewer Steve Huey wrote that Dr. Octagonecologyst "...attracted more attention than any non-mainstream rap album in quite a while, thanks to its inventive production and Keith's bizarre, free-associative rhymes."

Huey also states that Dr. Octagonecologyst represented "...the first truly new, genuine alternative to commercial hip-hop since the Native Tongues' heyday.

It appealed strongly to alternative audiences who'd grown up with rap music, but simply hadn't related to it since the rise of gangsta".

[10] The resulting album, The Return of Dr. Octagon released in 2006, was largely produced without Thornton's involvement, based upon three completed vocal tracks and reconstructed outtakes.

[7] Later, Thornton revived the character for the albums Moosebumps: An Exploration Into Modern Day Horripilation and Space Goretex.
