There are a lot of unknown DJs out there that actually have talent, but no ones gives them a change just because they aren't well known. I know some DJs that actually mix pretty good and are playing at crappy places that hardly anyone goes to, just because they aren't known and the big club owners just want the same clowns playing at their clubs.
As for Marcelo addax my little 12 year old sister can do what he does, just gotta tell her, play this song, than this song, than this song and she doesn't need to know how to mix.... heck...... i can program my cd player to play "all the hits" and we would have one heck of a party with the standards for DJs at some places.
