At the beginning of your 40th birthday party is usually when your family and friends will want to catch up and mingle. The DJ's entertainment and music at this point can be kept low key; it would be an idea to take into account the lighting and atmosphere in the room so people feel comfortable settling in to the birthday party. You could hire an outdoor heater if outside or consider booking a catering company to supply some light finger foods. Leave it to our DJ to choose a soft blend of great background music suited to your 40th birthday party.
