The DJ's job is both to inform and entertain in equal measure,done correctly the DJ's enthusiasm for the records he's playing should be picked up by the audience,agree with shane, roger banks is a great example of this,seen many a DJ with mega bucks collections looking totally disinterested while doing a set,use of the microphone intelligently creates atmosphere,golden rule,limit the alcohol intake,stylus on slipmat sounds sh*t
