I know this will probably draw the ire of the young crew and I am probably missing something obvious .... but

I was reading the music liftout in the local paper and it was proclaiming the virtues of some DJ or other.
It occurred to me ... How does a DJ actually perform? ... Surely they are just playing someone elses music and at best adding some additional drum and bass into the background.

Is this really performing? or is it scamming hundreds of people into paying to see someone spin some disks created by people and bands far more talented than they are??
