Adelaide's party bookings tend to happen in one of two places: a hall or club room hired for the night, or somebody's backyard in the suburbs. Both come with nothing in them, so the band brings the whole show, and the size of the lineup you book is mostly a question of what fits and what the space can take.
The city is compact enough that travel is rarely the issue it is in Sydney or Brisbane, which means you can shortlist on the music instead of the map. Watch a live clip of each group before you decide, and pay attention to whether people are up and dancing or politely watching.
Top picks are the acts in this category in Adelaide, with the most visible client reviews first, then rating; premium listings break remaining ties.
For a suburban backyard, a three-piece usually has the right volume and footprint. A hired hall with a hundred people can take four or five and will feel empty with fewer. Give the band the room size and the headcount and let them recommend, since they would rather do that than turn up to a space they cannot fit into.
Number of players first, hours second, then whether they are supplying lighting and a PA or you have something already. A Saturday night in December sits at the top of the range and a winter weeknight at the bottom. The from-prices on this page are live, so use them to set expectations and then enquire with your date.
Most are happy to work from a short list you send ahead, and many will learn one special song if you ask at booking. Handing them a request on the night is less reliable, because it either is not in the set or it does not suit where the room is at. Send your must-plays and your do-not-plays in writing.
Two or three sets across the evening, most often forty-five minutes each with music in the gaps. Three hours on site is the usual booking once you count setting up and packing down. If your night runs longer than that, ask about an extra set rather than assuming it is included.
A band plus lighting on one household circuit is more than it can carry, and it usually goes in the middle of a song. Ask what they draw and get them onto more than one outlet, ideally fed from different circuits.
Hired rooms come with a licence condition on when the music ends, and it is usually earlier than people assume. Confirm it with the venue before you pay for a band to play a final set that cannot legally happen.
Fringe and the Festival take a lot of Adelaide's musicians out of circulation for weeks, and a party in that stretch competes with paid festival work. A slow reply in March is not disinterest, it is a diary.
