Folk is doing several jobs as a word, and choosing without noticing is how a quiet memorial ends up with a bodhran in it. Celtic and Irish material, Australian bush and colonial song, and contemporary acoustic writing are three separate trades sharing a label. Say which you mean in the opening line of your enquiry and the shortlist halves itself.
It is a genuinely short list either way, so enquire with several performers at once rather than waiting on replies in turn. If nobody suits, an acoustic soloist or a small string act covers a lot of the same ground for a ceremony or a lunch.
Top picks are the acts in this category in Adelaide, without a review, rating or premium ranking: all these sort keys are tied.
For a small group sitting close, genuinely yes, and it is why this trade keeps getting booked for ceremonies in the Hills and out among the vines where there is no outlet for a kilometre. The limit is honest physics rather than willingness: past about fifty guests, or in any breeze, a voice and a guitar stop reaching the back row. So ask what battery gear they own and how many hours of charge it holds, instead of assuming the unplugged version scales up.
Typically a processional, something through the signing, a recessional, then a quiet stretch while the photographs happen. Expect their own repertoire to carry most of it, with a couple of your choices worked in. Get those choices across weeks ahead, because this trade tends to sit with a request and build its own version rather than reading a chart on the day.
The footage and the reply are your evidence. Find a clip of them playing outdoors rather than a studio track, because a lawn is unforgiving and a produced recording hides all of it. Then ask which tradition they mainly work in and whether they can lead a room in singing, since a performer who can do that changes a wake or a family gathering completely.
It depends whether one person is switching instruments or a second player is turning up, and those are very different numbers. Plenty of folk performers carry three or four instruments themselves, which is exactly why they are worth hunting for. Confirm which version you are being quoted before you set two figures beside each other.
A stone barn or a tasting room in the Barossa or McLaren Vale rarely has a sound system, and sometimes not a spare power point either. Find out what the performer runs off a battery and how many hours that gives you.
A bush dance needs tunes written for dancing and a caller to tell people what to do with their feet, and that is not the same hire as a performer with a song list. The mistake only shows itself once a hall full of guests is standing up waiting.
Adelaide's festival season commits a large share of the city's musicians for several weeks. A booking landing in February or March needs a much longer run up than the same booking in August.
