Defunct techno/underground DJ remix service based out of Dallas, Texas, which evolved from an earlier Hi-NRG remix service called Mixxx Masters (which was previously called NRG Mixxx). Metropolis put out 12 vinyl issues under the Metropolis name, the first six issues on single 12", the latter 6 on double 12". Four more double 12" issues were put out under the Glow name before the company closed.
