Imagine the room filled with the smoky, rich sound of a live saxophone as your guests arrive. That kind of atmosphere sets the tone for the whole night, but pulling it off takes some coordination. Since you are booking a month ahead, you have just enough time to lock down the right player before their calendar fills up.
Live music isn't something you want to leave to the last minute. Getting ahead of the timeline means you can sort through local pros, talk about song lists, and spread out the about $500 cost without wrecking your monthly cash flow.
That intro window is a hard deadline, not free money, and any leftover balance sitting on the card when the 18 months run out will get hit with standard interest.
