How to Find the Perfect Band for your Wedding
There are three ways you can go about finding and hiring a band. First, call a local or regional booking agency (get agency recommendations from friends, wedding planners or your venue) and ask for bands that fit your specific criteria. The agency will contact the bands that match your requirements (and that are available on your date) and put them on hold for you. Alternately, if you are good at shopping around on your own, you can look up bands directly.
Most of the best party bands have very extensive websites with videos, audio demos, pictures and song lists as well as professional contracting. You can look up their performance calendars and go see them play. Also, a band will typically hold your date for a certain period of time so that you have time to see them live. If you choose to retain their services, they will issue you a contract and require a retainer just like an agency would.
Another way to find quality bands is to ask your wedding planner or catering manager. Based on their experience they typically have insight as to which are the best. Some bands also have working relationships with planners who refer them on a regular basis so you might be able to get a vendor discount through them.
