The Ultramagnetic MCs Members: Who Started It All

The Ultramagnetic MCs were founded by Kool Keith (Keith Matthew Thornton), one of hip-hop’s most innovative and eccentric voices. The original lineup included:
- Kool Keith – Lead MC, founder, known for abstract rhymes and off-beat delivery
- Ced-Gee (Cedric Miller) – MC and primary producer, sampling pioneer
- TR Love (Trevor Randolph) – DJ and producer
- Moe Love (Maurice Smith) – DJ
The group also had notable affiliates over the years. Tim Dog became an unofficial member in 1989, and future beatboxing legend Rahzel served as a roadie early in the group’s career. Even KRS-One was reportedly close to joining Ultramagnetic MCs before forming Boogie Down Productions.
Critical Beatdown: The Album That Changed Hip-Hop

Released on October 4, 1988, Critical Beatdown introduced sampling techniques that would define the golden era of hip-hop. Producer Ced-Gee pioneered the use of “chopped” samples—rearranged and edited to change context—a technique that became fundamental to hip-hop production.
What many don’t know is that Ced-Gee also produced the majority of Boogie Down Productions’ seminal Criminal Minded (1987), though he went uncredited. Both albums feature heavy James Brown sampling, which became a staple of the genre in the years that followed.
For fans who want to honor this landmark album, our Ultramagnetic MCs Critical Beatdown T-Shirt celebrates the record that proved hip-hop could be experimental, intelligent, and groundbreaking all at once.
Key Tracks from Critical Beatdown
- “Ego Trippin'” – Their breakthrough single (1986), the first hip-hop song to feature the “Synthetic Substitution” drum break
- “Travelling at the Speed of Thought” – Featured extensive sampling from “Louie Louie”
- “Funky” – Used a Joe Cocker piano sample later famously used in 2Pac’s “California Love”
- “Give the Drummer Some” – Produced by the legendary Paul C., who also engineered most of the album
- “Watch Me Now” – Showcased Kool Keith’s abstract, stream-of-consciousness style
The Sampling Revolution

Before Ultramagnetic MCs, sampling in hip-hop was relatively straightforward—loops were used largely intact. Ced-Gee and the group changed that by “chopping” samples into smaller pieces and rearranging them to create entirely new compositions. This technique became the foundation of golden era production.
Their 1986 single “Ego Trippin'” was historic for another reason: it was the first hip-hop song to use the “Synthetic Substitution” drum break, composed by Melvin Bliss. That drum pattern would go on to become one of the most sampled sounds in music history.
Kool Keith’s lyrical approach was equally revolutionary. His abstract, stream-of-consciousness style—full of bizarre imagery and unexpected references—influenced artists like Pharoahe Monch from Organized Konfusion and Ghostface Killah of Wu-Tang Clan. Keith would later push these boundaries even further with his solo work as Dr. Octagon, Dr. Dooom, and Black Elvis.
Beyond Critical Beatdown: The Full Discography

After the success of Critical Beatdown, Ultramagnetic MCs went through various phases:
- Funk Your Head Up (1992) – Their Mercury Records album, featuring the hit “Poppa Large” (remixed by Da Beatminerz)
- The Four Horsemen (1993) – Featured guest production from Godfather Don
- Big Time (1997) – Released as “Ultra” by Kool Keith and Tim Dog
- The Best Kept Secret (2007) – A reunion album featuring the original lineup
- Ced Gee X Kool Keith (2022) – Their most recent collaboration
The 1997 album Big Time holds special significance—released under the name “Ultra,” it reunited Kool Keith with Tim Dog and featured their sharp-tongued commentary on the state of hip-hop. For fans of that era, our Ultramagnetic MCs “Industry Is Wack” T-Shirt captures the unapologetic attitude that made them legends.
