totally toally understand where you are coming from here.
I`d say that the basic fact is that you will and probably do encounter prejudice or stereotyping from your acid techno history.
But it is a history to be proud of, and rightly so.
It`s all very well to say "oh a true techno fan would never stereotype and blah blah" but basically, you know the score, you get put into a box by people.
I`ve been in the same position and am having to do the same thing, use a totally anon name.

Aliases are the way, it`s your music at the end of the day, if it`s good, it will catch on, and if you have the dollar or the butt sucking talent, then get some good capitalist schweinhund marketing on the go too.

Good luck, and basically go for it man, you can still keep up the london stuff too, split your time, 2weeks other stuff, 2 weeks acid, or whatever.

If you start an alias (and I think the henry cullen one everyone knows is DtD), then try to keep it as anon as poss for as long as poss I reckon, although obviously be contactable etc
