I'd just like to make the point that drum and bass is prime chav music.
This is a myth you barely get any chavvy types at drum and bass events, they tend to be far more into cheesy dance/pop garage/blazing squad/american r&b (J-lo, Ja Rule etc.).
that might be true in some cases, but not in general IMO.
d&b events are pure chav fests. i've been to bounce in norwich which is one of the top 3 d&b nights in the country, and also seen ecksman at the old fire station in oxford. both were rammed with chavs, but it was a surprisingly good atmosphere (that can be put down to what everyone was taking, but still it was nice).
