Mills characterized the new Detroit sound like no one else ; together with Mike Banks (and later also with Robert "The Vision" Hood) he founded Underground Resistance and brought the Detroit Techno sound of the early 90's into the clubs and onto turntables all over the world.
The trio tailored the soundtrack according to life in their hometown : harder, faster, more dangerous but still sensitive. On their self-entitled Underground Resistance label, this conglomerate of musicians released 12-inch vinyl records, mostly instrumental but appearing as well with vocalist Yolanda Reynolds. Older Disco and Soul traditions founded by Motown Records (then seated in Detroit) have been lifted to another level and voices of the 60's have been combined with the 90's sound.
Sound documents of Jeff Mills' UR phase, are the releases of the 'X-101', 'X-102', and 'X-103' project series, released in Europe by Tresor Records under UR license. Apart from his work in the studio, Jeff Mills also constantly maintained his DJ-career, thus he was able to pursue the actual party movement worldwide but he eventually followed New York's "call" and installed himself in one of Manhattan's largest clubs : the Limelight. In the long term the distance made an intensive cooperation with Banks and Hood impossible, so Mills departed from the two.
