One chair, a small amp and a power point is the entire technical requirement, which is why this is the easiest live music to put into a Brisbane function. It also means the two questions that matter here are physical rather than musical. Where is the shade, and where is the nearest socket.
The list is short, so shortlist three and send them all the same details at once. Tell them the hour, the room and whether guests are meant to be talking over the top, because a player who knows they are working under conversation performs a different job from one who thinks the room is listening.
Top picks are the acts in this category in Brisbane, without a review, rating or premium ranking: all these sort keys are tied.
One player with a hollow body guitar has almost no running costs, which is why this sits at the affordable end of live music. Hours and travel move it, and adding a double bass or a singer means paying for a second professional. The live from-prices beside each Brisbane listing here are what local players are quoting now, so work from those rather than from a figure in an article.
It is a sensible way to use one, since the same player covers the aisle, the signing and then the first part of dinner. The Brisbane wrinkle is that the ceremony is nearly always outside and the meal inside, so there is a pack down and a second setup in the middle. Leave a quarter of an hour clear on the schedule for that shift and nobody ends up rushing.
One power point a few steps from where they sit is the entire technical requirement. Riverside lawns, park rotundas and acreage blocks west of the city frequently have nothing within a safe cable run, so confirm it before committing to the spot. A good number of players own a battery amp that covers a short set for a modest crowd, so ask what theirs will actually handle.
Jazz guitar runs through a small amplifier, has a warm rounded tone, and it swings, which puts it firmly at drinks and dinner with a glass in hand. Classical guitar uses nylon strings, usually goes unamplified, and keeps a certain recital formality even playing something modern. Where a Brisbane wedding has a seated ceremony and then a long evening, plenty of players will do both, so raise it early and ask.
A wooden guitar left in a Queensland afternoon goes out of tune between songs and stays there. For anything outdoors from October to March, arrange proper cover for the player and their instrument before you talk about the set list.
A fair number of solo players run rhythm section recordings underneath what they play. That gives you a fuller sound and there is nothing wrong with it, but it is not the same booking as one musician alone in the corner. Find out which one is arriving.
None of these players carries a visible review, so judge them on footage filmed at somebody's actual event rather than a studio take. Holding a dinner floor over the noise of a hundred talking guests is a skill no clean recording will ever show you.
