Fifteen minutes from the centre of Perth is the whole story of this page. Guildford is about a quarter of an hour from central Perth, so the list below is effectively the entire Perth pool with almost no travel attached to it, and the acts at the top are the ones carrying real client reviews rather than the ones living nearest. A few do give Guildford as home, which is more than most outer suburbs manage.
Behind the town is the Swan Valley, and that's what makes the format question different here. Vineyard lunches, cellar-door functions and weddings in a garden want an act that works at conversation volume for the first few hours and then lifts, which is a jazz group, a trio or a classical guitarist rather than a pub cover band. Both sorts are in the list. Decide which half of the day matters most before you start reading profiles.
Top picks are the nearby performers with the most visible reviews, then rating, then the closest; further afield the closest come first, and premium listings break remaining ties. Distances are straight-line from Guildford. Ask each act whether they travel to your venue and what that costs.
Hardly ever, and the charge is small on the rare occasion it appears. Guildford sits inside the metro area and the valley is only a few minutes past it, so this is ordinary local work for almost every act in the city. The exceptions are acts based well south, around Rockingham or Mandurah, who are looking at an hour or more each way and a late run home.
Something that can play under conversation without disappearing: a classical guitarist, a jazz trio, a duo with a light touch. A cover band built for a pub will be too loud for a seated lunch in a cellar door, and the good ones will tell you so themselves. Ask any act on your shortlist how they run the first hour, because that answer sorts the two types quickly.
Players and hours decide most of it, and here you're paying for the music rather than the road. Where the figure moves is production: a garden with no power and no stage means the band brings everything, which costs more than loading into a room that already has a PA. Compare the from-prices on the cards for acts of the same lineup size rather than across formats.
Because the top of this list is ordered by acts with visible reviews from real clients, then their rating, then distance. Near Perth that ordering costs you almost nothing, since everything on the first screen is a short drive anyway. Further down you'll find the acts that actually live in Guildford and the neighbouring river suburbs.
A valley wedding often needs quiet music for the ceremony and lunch, then volume after dark. Ask whether one act covers both with a change of set, because two bookings costs more than one that stretches.
Swan Valley venues sit close to houses and most have a hard stop written into the booking. Get that time from the venue before you brief the act, so nobody is negotiating it at eleven o'clock.
A city act reaching Guildford has a quarter of an hour on the highway and no reason for a large travel line. If one appears on a quote, it's a fair thing to ask about.
