Shy Fx played the violin professionally before making Original Nuttah.
Or no he didn't, like most electronic music producers he sat down and stuck bits together, learning the theory afterwards.
I'd like you name to the best producers that have a 'genuine musical background' (what is that supposed to mean, anyway?) instead of learning to produce and gaining knowledge of musical theory along the way. If anything, a knowledge of what's wrong and right, stops you being groundbreaking. Jungle/d&b wasn't born in a classroom.
Don't think you can't produce d&b without knowing your octaves from your semi-claves, your tones from your baritone and your Reese Bass from your ass.
Adam F, Goldie, Fresh, Benny Page, Marcus Intalex, Sabre, Calibre, ST. Files, Commix, Chase & Status, Pendulum, Concord Dawn, Roni Size, DJ Die, Logistics, High Contrast, London Elektricity, Danny Breaks, 4 Hero, Photek, LTJ Bukem, PFM, Peshay.....just a few off the top of my head that had a musical background - however basic - that will undoubtedly make a difference when producing.... you cannot argue this.
When you write MUSIC it helps if you understand MUSIC .... you dont need to be fuckin Mozart, it's just a suggestion that this guy might find it handy to learn some basic piano skills ( for example) etc before worrying about shelling out hundreds on PC's etc...
And "knowing the difference between wrong and right" doesn't stop you from being groundbreaking... either you are in tune, or you are not. Either your bassline co mpliments your melody or it does not.
And, to be fair, old skool (& Jungle) was rarely very musical (other than your pioneers such as Joey Beltram, 4 Hero etc), it was ripped off samples with B-lines that were universal; nowadays it is far more important to express yourself with music and soul, rather than playing 2 notes and then copying and pasting them into your B line, melody, etc.
Or you run the risk of making worhtless throwaway music - and nobody wants that......
