Ask the venue for its live music finish time before you fall for any group on this page. Sydney's inner suburbs have put apartments alongside rooms that have had bands in them for decades, and the condition in the hire agreement is usually earlier than anybody expects. There is no sense booking music built for eleven o'clock into a space that kills the power at ten.
Once that number exists the rest is straightforward. This is dance floor music, the bass and drums are the point, and it does its work in the back half of a night rather than underneath a dinner conversation. Tell the band which of those two evenings you are buying and they will build the sets to suit.
Top picks are the acts in this category in Sydney, without a review, rating or premium ranking: all these sort keys are tied.
Listen for what the room is being asked to follow. In one, the bass line is the melody everybody moves to and a single groove can run for six minutes without a chorus in sight. In the other, the voices are the event and the crowd is meant to sing along with them. Most Sydney acts here can go either way on the night, so tell them which one you have in your head before the set list gets written.
For the part after the plates are cleared, yes, and it is one of the better bookings for a crowd that needs pushing onto a floor. For the speeches and the meal it is the wrong tool and a good band will say as much. Split the night in your enquiry, give them the finish time from the venue, and let them work backwards from it.
Loud on purpose. The low end has to arrive in your chest rather than your ears, and a band asked to play this politely delivers something nobody enjoys. Accept that or book a different trade. Then look at the room for anything soft at all, because a tiled Sydney space under a high ceiling turns five musicians into an unbroken roar, and it is you the venue rings afterwards.
Write to every one of them at once. For a city this size the working pool is thin, and the groups you would want have usually sold their December Saturdays before winter is over. When the date cannot move and nobody is available, look through the soul and covers listings instead, where a fair few of these same musicians turn up playing much of the same repertoire under another name.
This music stands or falls on two players and a promotional edit will bury both of them under the brass. Ask for a clip where you can actually watch the kit and hear the bass before you commit to anything.
Brass players around Sydney spread themselves across several groups, so the faces in a clip are not a promise about your date. Put that question in the first email: is the section permanent, or assembled gig by gig.
Nobody talks over this music comfortably and it is unfair to ask a band to try. Put a playlist or a soloist through dinner, then bring the band on when the floor opens, and two shorter sets late will do more than four polite ones.
