Mobile D.J'ing is far harder (in terms of creating an atmosphere) than Club D.J'ing. For instance those attending a club are going there knowing that there is loud music, flashing lights and even paying an admission fee to get in. They are not going there to chat and catch up with family members they haven't seen for years. In short they are going there with the sole purpose to have a good time.
At Most Mobile Functions, guests are there by invitation and politeness, they may hate Disco's with a passion and much prefer a game of dominoes or Bingo. Often they've been dragged away from the tele by their Wives to attend. Most function guests are happy picking through the buffet and chatting to people they haven't seen in years. The D.J and dancing can often be the farthest thing from their mind

.
Equally some clubs are now employing personality D.J's. This isn't personality in the sense of a famous D.J more a term used to describe a D.J who uses a mic. If you can mix well AND are confident using a Microphone then you will have the advantage over those D.J's who purely mix for 6 hours a night. Both the clubs i've worked in have required the use of a mic - especially during theme nights and doing risque' adult games

. Some city centre clubs would never do anything like this, it depends on the area / clientele' / management - but the more flexible you are with regard to skills then the more likely your chances at getting in to a venue.
