Dance music enthusiasts are almost certainly the most label-conscious people in the record-buying world. How else can you explain the bickering over new Perlon signings, the ubiquity of the compound adjective “buy-on-sight,” or the hastily depleted stocks of anonymously-produced 12″s? We follow our favorite DJs and producers, naturally, but a record publishing operation with vision and taste is very often the best guide to the sounds we thirst for. 2009’s cream of the crop — labels like Running Back, Uzuri, Prologue, Dial, Sound Signature, Blueprint, Apple Pips, and Time To Express — did more than narrow the field of available records, but sharpened our expectations of what new music should achieve. And the mushrooming of secretive private presses (many of them fostered by Hardwax’s distribution) yielded results that were just as rewarding. But from where I’m standing, these five labels loomed largest.
