Emerging from the debris of the recording sessions for latest album We Were Exploding Anyway, comes this craftily-compiled EP featuring six brand new tracks (and one new edit), because surely nothing is too good to throw away. The band obviously feel strongly enough about how special these songs are, as they’ve compiled limited edition artwork for the release and are offering two tracks (unavailable elsewhere) to folks who place a pre-order. Another sign of how serious they are about the content comes with the announcement that they’re about to take it out on tour. So it must be all killer and no filler, right?

Well, kicking off with a bit of a duff extra we find that ‘Tiger Girl’, having been cut down from an admittedly lengthy 10:37 to a mean 3:36, has its emotional peaking effect blunted somewhat. Allowing yourself to dwell and soak up the rhythm is often far superior to the short, sharp hit. A bad start then but, thankfully, the remainder of the EP is jam-packed with crackers.

‘The Wrong Shape’ ebbs and flows dynamically and, as such, is somewhat reminiscent to ‘Crash Tactics’. Comparison between the two actually results in this new release sounding just that bit stronger. ‘Pacify’ crawls into view, sounding much like the bone-chilling opening to Baroness’ ‘Rays On Pinion’, like a hundred fingers running their way round a hundred glasses, whilst ‘PX3′ expounds further on that progressive element pulling in a wholesome heartbeat bass to help out the manic piano. ‘Beats Like A Helix’ grabs great fistfuls of computer-generated beeps and throws drum and bass at it, whilst ‘Guitar Cascades’ is a collapsing, submerged, massively cathartic wall of noise. The real find here, though, is ‘Sawtooth Rising’ which is exactly the one missing element from 65DOS’ exploration of dance music that so inspired ‘WWEA’. It’s colourful, rich, buoyantly building, exceptionally brutish and fused with the classic buzzing signature of mind-melting euphoric trance.

So instead of finding six that didn’t deserve to make the cut, ‘Heavy Sky’ marks the brilliant completion of a stunning and, clearly, devotional body of work.
