On "Fireworks," the mood is malevolent with synth shrapnel crisscrossing a stately, choral progression.

Sam Shackleton offers up another must-have release in the shape of this expansive double pack. Lead cut "Fireworks" is classic Shackleton - a skittering dubstep/dub techno fusion that makes delicious use of echo-laden congas, foreboding noises and distant, Middle Eastern melodies. It's utterly spellbinding. T++ remixes, delivering a ricocheting dub take. On the second disc, Shackleton reveals "Undeadman", a kind of bizzaro universe mix of "Deadman". It's pleasingly creepy, working odd samples and strange found sound around a solid, dancefloor-friendly rhythm. Flip for an excellent remix from Mordant Music, which makes brilliant use of a live dub bassline.
