Music never exists in a vacuum — every scene and sound evolves from the non-stop exchange of ideas between different groups and cultures. Traditions get passed down from one generation to the next, and then individual heads take influence from their own unique perspective. Sometimes, certain people strike upon fusions that spark massive new movements, but even those rarest innovations came from somewhere.

Jon E Cash knows this more than most — the legendary beats he started putting out at the turn of the millennium had their own disparate roots and influences which he had the motivation to put together into a sound he called sublow. There wasn't any other reference point for this music — when he took the first white labels of 'Drop Top Bimmer Kid' into Blackmarket Records in Soho, London, he had to describe it to a puzzled Nicky Blackmarket and J Da Flex as being, "between garage and hip-hop."

Playing catch-up in 2004, Rephlex Records nodded to sublow when trying to introduce a wider audience to the sounds which had been tearing up the London underground. "Grime. Sublow. Dubstep... It's Music. Different people call it different things depending on when they discovered it." But Jon E Cash's sound was rooted in more than the UK garage that had dominated the clubs through the late 90s, reaching way back to his pre-teen days when the first waves of hip-hop culture crossed the Atlantic and broke in the UK.

25 years on, it's a fine time to reflect on the impact of the music Cash made at the turn of the millennium. History looks back favourably on what he and the Black Ops crew were doing with sublow in the early 00s. The timing meant it ran in parallel with what was happening over East with Pay As U Go, Roll Deep et al, and of course there was crossover. Every DJ and every MC was on the hunt for the best beats they could find. But there's a whole different swagger to sublow — a different web of influences, a different intention and so a different outcome. It's still there in the beats Cash is making more than 20 years later — his 3dom Music label is carrying upfront productions with that sublow DNA coursing through their veins. Whatever the beat or the tempo, the drums are still hard as nails, and the bass is tuned for maximum rave damage.
