The organisation runs out of a former railway station in the West Australian town of Geraldton, where it holds workshops, provides rehearsal space and stages live performances.
Local punk outfit RATSALAD, which has just returned from a European tour, is among the bands to perform at the venue, leased with money donated by another band that started out in Geraldton: Spacey Jane.
Geraldton is big on sport and agriculture, explained Sarah Hinton from Regional Sounds, but promoting the town's music scene will help everyone.
"People rail against the 'Dero Gero' tag, and it doesn't help when Geraldton's growth is off the charts lately, it's a great place to live," she said.
"I'm just hoping that people can give a little to make a big change, not just for our artists, but Geraldton as a growing regional city that's trying to be an adult."
The pitch for donations is one of more than 300 as part of the inaugural AusArt Day on Thursday, an initiative launched by federal arts funding body Creative Australia.
The Regional Sounds fundraising drive has a way to go - its tally is sitting on $25 of a $20,000 target.
Creative Australia allocated $286 million in arts funding in 2024/25, as the sector contends with reduced discretionary spending and higher production costs.
Creative Australia board member Alex Dimos wouldn't be drawn on whether AusArt Day is an acknowledgement that government funding isn't coming close to what the sector needs.
Dimos, who is also on the board of Philanthropy Australia, instead sees AusArt Day as a recipe for the kind of ambition Creative Australia wants to encourage in the nation's artists.
"AusArt Day is like a sponge cake - governments and Creative Australia bake the base, solid, reliable and essential," said Dimos.
"What they've done here, which I think is quite clever and strategic, is they're asking philanthropists to consider adding the icing, that layer that makes it a little bit more special."
Whether this analogy works may depend on the artist or organisation in question - some participants in the donations drive, such as the Australian Design Centre in Sydney, missed out on the longer-term government funding required for everyday operations.
The AusArt Day platform has certainly brought some original ideas to light, such as the Fix'Em Up Truck, a mobile initiative to repair musical instruments in the Northern Territory, where remote communities are humming with music.
"Guitars are often shared among numerous bands, drumkits used around the clock, and PA systems pushed to the limit to keep the music going. And don't mention the red dust," reads the funding pitch.
Australia may lack the culture of prominent philanthropy seen in the US, but AusArt Day does have some celebrity backing, with Collingwood AFL captain Darcy Moore supporting the Melbourne International Film Festival.
Actor Rob Collins is part of a telethon at Brown's Mart theatre in Darwin, while singer Kate Miller-Heidke is supporting Queensland's Woodford Folk Festival.
