No stage, no announcement, no moment where everyone has to stop what they are doing and face the same direction. The singing simply arrives where your guests already are.
Roaming singers move through a room and perform properly, a few feet from people rather than across a room at them. Opera that lands in your chest during a drinks reception, close harmony over dinner, a duo working table to table between courses. Because they move, every part of the room gets its own moment instead of the same few tables near the front.
Powerful enough to stop conversations dead, but light enough that they never take over the day. It is live vocal performance that fits around your schedule rather than needing a slot in it.
