We never quite know what to expect from leftfield explorer Jon Hopkins, but we know it will be worth a listen. Immunity, his fourth solo album (he's recorded two others, one with Brian Eno and another with King Creosote), doesn't disappoint. Rooted in shuffling, forthright and occasionally off-kilter rhythms, it melds hazy, late night atmospherics and subtle melodies with intense, droning chords, woozy electronics and all manner of inventive noises. It's a blend that repeatedly pays dividends, from the mournful pianos and jumpy rhythms of "Breathe This Air', to the crystalline, soundscape ambience of "Abandon Window", and glitchy wonkiness of "Form By Firelight".
