Silicon Scally and Fleck E.S.C. need no introduction at this stage. Both artists are veterans not just of Sheffield's Central Processing Unit label but of modern electro as a whole, with the pair having decades of skin in the game at this point. Their new release, a four-track EP entitledSlipwhere Silicon Scally handles the first half and Fleck E.S.C. the second, carries itself with the adventurous confidence of a record made by masters of their craft.

Slipopener 'Phased Array' is exactly the kind of top quality machine-funk tackle you'd expect from this meeting of minds. The beat programming is deliciously tactile from the off, hissing and clanking like machinery in an old Detroit factory. The feel of 'Phased Array' is altered, though, when the chords come in, a series of alternating floating sounds which give the track an altogether eerier feel. When all of this is coupled with the otherworldly synth blurts that periodically force their way to the front of the track, the overall effect is a piece of real depth assembled by an expert practitioner.

'Phased Array' is followed up by 'Stax', another brilliantly propulsive number. Here we find the drum beat - one which is a little reminiscent of that Kraftwerk tune about the numbers, no less - once more offset by some decidedly more shadowy synth work, all while arpeggiated keyboard licks work against an intricate web of basslines, chords and unidentifiable flying synth tones.

Fleck E.S.C. opens theSlipB-side with 'Good Ride', a number where the nudge-wink title is borne out by a track built around looped snippets of sighing vocals. That said, with a bassline that sounds like a blurting old landline telephone, a ghoulish synth lead and all manner of motion-sick breakdowns, the 'ride' in question could just as well be aWipeout-style whizz through hyperspace as anything more suggestive. 'Good Ride' also sets itself apart from the other joints here by showing off a swaying halftime breakdown.

'Intox Remedy',Slip's closer, wraps the EP in a manner which continues some of the trends of the record's earlier tracks - richly tuneful chords, precision-engineered broken beat drum programming and a wide palette of delightfully unusual synth tones are all present and correct. However, there is also something about the chords here which pares back the eeriness of previous joints for a bit more of a wide-eyed, stargazing feel, and as such 'Intox Remedy' sees the record out by placing the listener firmly back in the cosmos.

Tough enough for the dancefloor and intricate enough for home listening, theSlipEP is a fabulous collaboration from two of the most respected voices in the electro game.
