songs and introduced new group affiliate Tim Dog. A variation of the "A Chorus Line" instrumental was used as the basis of Tim Dog's debut single, the Ced Gee-produced "Fuck Compton", which became a modest hit and is credited with helping to spark the East coast/West coast feud of the mid 1990s. The group went on a hiatus for several years, breaking up temporarily in 1990. They returned on Mercury Records in 1992, with the album Funk Your Head Up. The album received a muted response, in part because many tracks had been given a commercial sheen, having been remixed by outside producers at the label's insistence. Alternate mixes of this album's songs along with unreleased tracks from the sessions have appeared on later compilations. The song "Poppa Large", remixed by Da Beatminerz, became a hit and remains a staple of Kool Keith's live show. The song's video featured Keith in a straitjacket, his bald head encased in a birdcage. In 1993, the group released the album The Four Horsemen, which featured guest production and vocals by Godfather Don, who produced solo Kool Keith sessions in 1992. Some of those tracks appear on The Four Horsemen, and also on Cenobites. The former was the last official album the Ultramagnetic MC's released until their 2007 reunion. There were many semi-legitimate and compilation albums to follow, the most official of which was Next Plateau's The B-Sides Companion, which featured a new song, some unreleased 1989 songs recorded for a second Next Plateau LP and most of the group's classic singles, albeit in newly remixed form. Ced Gee and Moe Love both provided demos and unreleased songs spanning the group's entire career to Tuff City for a series of four albums which were released without Kool Keith's consent. A live album, Brooklyn To Brixton, was announced but abandoned. As a reaction to Ced and Moe's involvement in the Tuff City releases, Kool Keith and Tim Dog reunited on the album Big Time, released under the name Ultra in 1997. Kool Keith went on to record many solo CDs, including several under aliases such as Dr. Octagon and Dr. Dooom. His abstract rhymes and syncopated, off-beat delivery influenced many rappers, including Pharoahe Monch from Organized Konfusion and Ghostface Killah of Wu-Tang Clan. In 2001, Ultramagnetic MCs released a single, "Make It Rain" / "Mix It Down". Two other songs, "Baby, I'm Mad" and "Who
