I think there should be a nice combo of seasoned pros and talented newcomers. Probably only one or two newcomers though. That way you get something fresh but you also get the stuff that you know you like and is good, plus u keep that good ol' Brainy flavour.
Previously, dj's for the brain have consisted of, Kam, Haze, Adam Bomb, Scoob-E and Sam Hill, with appearances by 12inch, Gway and Damnation. So personally i think you should start with them.
As newcomers, some people have suggested Dr.J, sure he plays some good stuff, but too many times I've seen him clear a floor like nobodies business. No offence ment Dr.J, it just means that there is more for you to learn, as does everyone.
Aside from Dr.J there are the likes of Peroxide who hosted and played at the rather large Albany party, Llewelyn who also played at the Albany party, and Sez who put on the Journey.
I am sure there are plenty more newcomers and plenty of people who hav been djing for a while but havent been able to get out there who would jump at the chance to play at a big event such as the Brain. So as a solution to sorting through all these hopefulls i suggest a trial or audition of sorts, where people bring in a CD of theirs that they have mixed, apply in writing saying why it should be them that play. Once you have sorted through the undesirables you could then go on to getting the chosen to play live for you. This way you can truely deside which dj's would be the better ones to play.
Well thats enough from me. I shall now leave you to your own devices.
