[5] Paul C. also produced the Hip-House mix of "Traveling At The Speed Of Thought", which was used as the group's first music video, and was their sole release in 1989.

The single's b-side, "A Chorus Line", became one of Ultramagnetic's most popular 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",[5] which became a modest hit and is credited with helping to spark the East coast/West coast feud of the mid 1990s.

[5] 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.

The song "Poppa Large", remixed by Da Beatminerz, became a hit and remains a staple of Kool Keith's live show.

In 1993, the group released the album The Four Horsemen,[5] which featured guest production and vocals by Godfather Don, who produced solo Kool Keith sessions in 1992.

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.

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 2004, the original versions of the Next Plateau singles were finally released on CD as bonus tracks on the remastered Critical Beatdown.

In a 9 December 2005 interview on Houston's Late Nite Snax radio show,[6] Kool Keith confirmed rumours that the Ultramagnetic MC's had reformed and recorded a new album.
