This is a big one! The first impression you get from a band means an awful lot. We encourage everyone to go with their gut when it comes to this. If you instantly get good vibes from a bands video, then you’re on to a winner. If you’re a little unsure, then we suggest doing a little more digging.
Look at and request as much footage as you can get your hands on. In particular, if you manage to see any video footage with wedding/party guests in it, have a close look at them. Do they look like they’re enjoying the band? What kind of atmosphere has the band created for them? Is everyone up dancing, or is the band more of a sophisticated background act? Watching the guests reaction to a band can tell you so much.
