GAS isn't really meant for the club, but that's where I first heard it — a cavernous basement was hosting a night of experimental music, the definition of which was determined by the DJ. It sounded and felt like a symphony buried underground, beats programmed from a different galaxy. Pop didn't change the landscape of ambient music — it evolved its purpose, its tone, its movement.

In the 17 years since Pop's release, Wolfgang Voigt has continued to make music outside the GAS moniker and has co-run the influential electronic music label Kompakt. But now we have Narkopop, a welcome return to the murky depths, one that expands Voigt's beatless ruminations into a majestic disquiet.
