Not too much is known about E.M.M.A save for her brief association with Sully, her contribution to Keysound's This is How We Roll compilation and her 2012 debut release Rainbow Dust part II, the first record out on the label arm of London party crew Wavey Tones.

'Jahovia', her first 7" (and release full stop) on Dusk & Blackdown's Keysound imprint, released on July 1st with an album forthcoming later in the month, sees the London via Liverpool producer collaborate with Double Trouble's Rebel MC, refixing his classic, early 90s breaks driven classic 'Jahovia' – a number which united now retro, dubwise sensibilities with iconic rave and hardcore memes, creating a memorable tunes that still gets rinsed out today.

E.M.M.A's melodic refix is a massive step up in production values from the original, adding future gazing jungalist riddims, at the current in-vogue tempo of 130, that flip with the ease of a Russian gymnast into classic 3-3-2 dancehall patterns then effortlessly back again. Sitting atop the punchy, addictive drum work lies dub reggae infused, highly memorable melodic figures and chord progressions, taken from and made more prevalent than the original, played on dubby instruments and dreamy, floaty pads that twist and turn, pushing the track along in conjunction with the rhythmic beds provided.

Adding a pirate radio twist to proceedings is Rebel MC himself, whose laid back, almost spoken word delivery seems to sit on top of the mix rather than being buried/tucked away within it, giving the feeling of a live toast on the mutineering airways of London's buccaneer radio circuit in the 90s - a movement and underground culture so intrinsically linked to the grand linage and evolution of British dance music culture that we know today, that without it, who knows what music would sound like in 2013. It's a nice touch that is sure to bring nostalgic memories bubbling up to the surface of those who experienced those pioneering, hedonistic days first hand.

Stepping up on the B-side is Wil LV of Hyperdub fame who provides a tougher, more dubbed out version (if that is possible) of the title track. Adding to the track, a steppier riddim, a more prominent bassline and a heavily pitched, filter modulated vocal sample alongside organic, world percussion, Wil LV's dub version relies much more on the bed of bass and drums to push the track along, than the airy, melodic features E.M.M.A deployed so deftly, and that's no bad thing, as it provides a juicy contrast to two excellent but similar tunes.

All things said Blackdown's A&R policy of the last 18 months has been so on point that the rise of Keysound's status as one of the most important labels in the UK bass music scene and beyond verges on ridiculous. They are like an underground music 'Hit Factory' that keeps on delivering time and time again, pushing the boundaries of experimental, yet accessible Hardcore Continuum based music, in the process creating one of the only 'buy on sight' brands of 2013. Bring on the album Martin, I salute you!
