mmhhh.. well I remember when drumnbass wasn't around.. Most of the jungle records I listenned to on my trips to England were containing distorted snares and basses, a jamaican/carribean MC screaming on the top, lots of reverb/echo. I asked "that's ragga jungle right? not straight jungle" the guy told me "well, most jungle is like this"
Then... then a few years later, went back to england, I was at a friend, and he had all kind of CDs and records... I asked "what's drumnbass?" (it was all new at the time). He played a few records... and it was VERY different. It was clam, clean, no distorsion, almost "ellitist, only if you are driving a ferrari" kind of music...
NOW.. I think dnb has evolved and changed, harder, crazier.. But I understand why they picked a new name, coz at the time, dnb was very different from jungle... and now you rarely see jungle around unelss the label was known for this stuff years ago when jungle was *the word*.
I don't say hey guys I am right tatatatata, but I just wanted to share my own experience and understanding of all this.
