Bristol's emptyset have gained a cult following over the past three years with raw Pan_sonic-style techno and earthshaking, abstract live performances. The latter are documented on 'Material': Three massive freeform audio assaults of fractured basswaves interspersed with ominous silence. Unique.

'Fall Back – Live at Aldeburgh' documents a joint performance by Roly Porter and Dobro guitar / ondes Martenot player Cynthia Millar, recorded in late 2011. Its four tracks finely balance the subtlety of Millar's fragile instrumentations with crushing waves of Porter's industrial bass and drones. Excellent.

Two extremely intense variations of Emptyset's incredible recent 'Demiurge' album. First up Paul Jebanasam, who reprocesses the album as a whole with emphasis on guitar noise from Gravenhurst, ex-Vex'd man Roly Porter does a fine job spinning webs of tense cinematic sonics. Wicked.

Picked!

The Bristol-duo return with their precision electronics with this latest five-track EP. Less directly forceful than last year's 'Demiurge', it wields its power in unsettling spaces between metallic noise sweeps, throbbing tones and minutely detailed echos. Some of the best experimental electronics we've heard in a while.

Heavyweight Bristolian duo emptyset release their second full-length after 2009's epic self-titled debut and a corker for CLR earlier this year. Uncompromising and brash techno-rooted bass experimentations, a grittier, more primal take on bare electronics of Sähko and Raster Noton. Highly Recommended.
