Once you decide what your entertainment budget is going to be, then you will have a better understanding of just what you will be able to afford for wedding reception music. You are going to want to keep in mind that it will probably be a bit more expensive to hire a live wedding band than it will be for a professional DJ. Most DJs can cost anywhere from $250 all the way up to $1,500, where a live band can start around $1,200 and cost up to $5000 for playing at your entire reception.
Whichever form of wedding reception music you choose to go with, it is always in your best interest to try to see either your band or your professional DJ when they are playing out live. This will give you a great idea of their personality and professionalism as well as how well they work the crowd at the event. As long as you cover all of your bases, you are pretty much guaranteed to have wonderful wedding reception music on your special day.
