Tightly clipped break-stepping rollidge from Bristol's Gatekeeper. 'Atmosphere Processor' harks back to '06 styles from Toastyboy and those early Hot Flush releases, harnessing swooping subs and taut, body-deflecting drum programming with a crackled, droning ambient pressure. The flipside plays with hovering chords and deft, dynamic drum swerves with a blue jazzdub effervescence.
