Welcome to Bands -- DJ's -- Music. As soon as you confirm a wedding date and secure a location for your ceremony and reception you should begin making arrangements to hire musicians and or a DJ. The most popular music professionals are booked at least one year in advance. Usually a bride and groom will need music for the wedding ceremony, the social hour or cocktail (the hour just before the reception begins) and the reception. One month before your wedding date you should have a meeting with your musician(s) to confirm all ceremony music details.
