Planet Rhythm are back with a stellar new collab between glitch veterans SND and RTN; a vacuum-packed blitz of minimal dub and aerated space ensured by a trio of savvy spacemen. It's not the first time this supergroup have worked together, but despite that fact, it might just be their best work: 'Chain Reaction' pays homage to Basic Channel's now-defunct label of the same name, vocoded stabs pulsing below depth-charged kicks, while the chordal dub vibe continues throughout. 'Th.12.9' is like a stripped-back Barker bit, while 'Ice' and 'Locked' recall the clippy and atmospheric enviro-dub of GAS. '77' is the most fun, edging into swung, poppy territory.
