Listening to an Andy C set live is a must
I used to go to the Fabriclive most Fridays and also Ram Party @ The End for a while, but stopped because it caused too much disruption to my schedules. One thing that annoyed me was that Andy C is invariably scheduled to DJ from 3am or 4am onwards, I guess in order to keep the clubbers glued right until closing time. That meant getting out at 5am or 6am... not fun :/
Either way, my personal favourite D&B DJ is Andy C because he seems to focus much more on giving what people want and letting them have a good time, rather than trying too hard to "do their own thing" and end up just confusing people. Plus he's very talented to begin with, of course
The D&B Arena has really good recordings of past events (less of the recent stuff but plenty around 2002-2003) which is a decent substitute for actually being at the venue.
