In 1991, Detroit techno group Underground Resistance licensed a few of its productions to Tresor, an upstart label based in Berlin. Rather than release the tracks under its own name, Underground Resistance released them under the moniker X-101. The resulting six-track EP, which became Tresor's first-ever release, proved so successful that Underground Resistance and Tresor teamed up for two more releases: one as X-102 (Explores the Rings of Saturn, 1992) and another as X-103 (Atlantis, 1993). Though Underground Resistance was a collective at the time -- comprised of Mike Banks, Jeff Mills, and Robert Hood -- Mills is often credited for helming the X-10... releases, with Hood as his co-producer. ~ Jason Birchmeier
