The pool of rock bands available here is genuinely small, smaller than the equivalent list in any eastern capital, so treat this as a page to enquire across rather than to pick one from. Message three or four on the same day and be prepared to look at cover bands and pub bands too, since plenty of Adelaide groups play the same material under a different label.
Volume is the negotiation that decides the rest. Adelaide's function rooms and halls vary enormously in what they can absorb, and a full rock lineup is unforgiving of a room that cannot take it. Sort the space, the power and the finish time before you talk about songs.
Top picks are the acts in this category in Adelaide, without a review, rating or premium ranking: all these sort keys are tied.
Number of players first, then the hours, then whether they are supplying a PA and lights or plugging into something the venue already has. Travel is less of a factor here than in the bigger capitals unless you are out in the Hills or wine country. The live from-prices on these Adelaide listings are what local rock bands are asking now.
Some can and they will tell you honestly how. Electronic kits, smaller amplifiers and a shield around the drums are all real answers, and a band that owns that gear has met a small room before. A band that simply promises to keep it down without changing anything has not, so ask what they will physically bring.
Floor space wider than you think, a load-in route without a flight of stairs, and enough power that several amplifiers and a PA are not sharing one household circuit. That last one ends more nights early than anything else. Get the band's requirement in writing and check it against what the room actually has rather than what the hire list claims.
Earlier than you would in a bigger city, because the choice here is narrow and the same handful of groups work most of the weekends. Anything in the festival stretch of late summer needs more notice again. If your date can move to a winter Saturday, ask what that looks like and you will usually get a better answer.
A club room or a hall booked for the night comes with a stated hour when amplified music stops, and it is usually earlier than people assume. Get it from the venue in writing before you pay a band to play a final set that cannot legally happen.
In a market this size the same musicians turn up in several bands and cover for each other. Confirm that the lineup in the video is the lineup you are booking, particularly the singer, because that is the part a substitute changes most.
Rock covers pub singalongs, stadium anthems and heavier modern material, and those crowds barely overlap. Read two or three songs off the list and you will learn more than any description gives you, because people sing along to the decade they grew up in and stare politely at everything else.
