Jazz is the most flexible booking in live music, which matters more in Perth than most places because the pool of players is small and the same musicians appear in several groups. A duo for a long lunch, a trio for cocktails, a quartet with a vocalist when the music is meant to be part of the evening. The lineup is the decision, and it moves the price more than anything else.
Nearly all of these groups give a Perth city address, which keeps travel simple inside the metro and expensive outside it. A fair number carry written reviews here. Read them, and for everyone else watch a full song and listen for whether the band is playing quietly by choice or just lacking presence.
Top picks are the acts in this category in Perth, with the most visible client reviews first, then rating; premium listings break remaining ties.
Count the musicians and then count the hours, because that is most of the answer. A duo for two hours at a Subiaco function and a quartet with a singer across a whole reception are a long way apart, and the opening figure beside each group belongs to its smallest combination. Ask for a figure against each lineup rather than one number for the band.
Two will comfortably fill a dinner for sixty and let people talk over the top. Three gives you a proper rhythm section for cocktails. Four with a vocalist is the point where the band becomes something guests stop and listen to, and that is the version you want if the music is meant to be an event rather than a backdrop.
Most Perth groups arrange pop and soul in a jazz style and will send a repertoire list if you ask. Give them any song that matters weeks in advance, because arranging for a small group takes time and cannot be done on the night. What they will not do convincingly is a straight rock cover, so keep requests inside the sound you booked.
It is one of the things they do best. Arrivals and canapes in the city function rooms need music that fills the silence without making people raise their voices, and a jazz trio is built for exactly that. Book them to finish when the speeches start rather than trying to play underneath a microphone.
If there is a tuned piano on site, say so early. It can cut what the band has to bring and opens up players who would rather use the real thing than a keyboard.
Music under a dinner and music people sit and watch are two different bookings from the same musicians. Tell them which one you want and the lineup they suggest will change.
