Pure, silken depth from Merc don Mark E, assisting Californian imprint Public Release celebrate its 20th excursion into sonic perfection. 'Shake' is stunning; a rattling, minimal vibe from the Carl Craig School of Chug*, a murky bassline tempered by quietly joyous strings. 'Shelter' kicks a set of congas down the stairs, adding the heavy swing of hats and rough percussion to blasts of radio interference. 'M-54', with its earthy arps, brings in waves of bright chords, while 'Shinkansen' slows things down with a deep Nordic freak out. Truly special. (*not a real school).
