Every aspect must be planned to the last detail. Factor in logistics—consider your neighbors, street traffic, timing—plus lighting and the setting, which will serve as your stage. Friends make perfect accomplices to keep everything under wraps. Never forget: the element of surprise is absolutely essential.
As for equipment, go for instruments that are easy to transport, simple to set up, and deliver solid acoustics. Imagine a brightly painted, fully equipped VW bus that can hold your band and a silent power inverter, or opt for a battery-powered amp. Lightweight and portable, it will be the key to making your serenade heard with crystal-clear sound.
