Sure, there's the tried-and-true wedding band that's been commanding the market in three states for three decades (and requiring a hefty fee just to show up), but if you're willing to look for it, new talent is always emerging. Go to music venues and scout out an act that catches your ear. Non-wedding bands are nearly always cheaper. Better yet, seek out music schools. Try a classical academy; you'll rest assured that your group has been formally trained in the tunes you're paying them to play.
