So, how much does live music cost? There are exceptions, of course, but we found these figures on a cost search for wedding and cocktail hour combined and they are quite accurate. Many couples will hire musicians for their wedding ceremony and cocktail hour and then another group or a dj for their reception. We are often asked if Jack will sing for the "first dances". He will either add dinner and the first dances on as an incremental cost of performing for the ceremony and cocktail hour OR he might start with cocktails and continue on through dinner and several dance sets with a DJ finishing off the evening.
