Subharmonic was an independent record label based in New York City.
It primarily issued music with strong ambient and dub music influence.
[1] Its sub-label was Strata Records, which issued all its albums in an opaque black container.
The label was founded in 1993 by music producers Bill Laswell, John Matarazzo and Robert Soares.
A falling-out with Matarazzo occurred during the mid-nineties, effectively ending the label's activities.
